Changing store view causes error - Requested store is not found

[mageage]

Magento CE 2.2.0 without sample data is installed.
After adding second store view in admin panel and change design configuration to:

• Default Store View: Magento Luma
• Second Store View: Magento Blank
  In frontend while changing store views I'm getting URL like this:
• http://magento-2.2.dev:8888/?___store=second?___store=default
  Which causes this error:
  {"0":"Requested store is not found","1":"#0 /magento-2.2.dev/vendor/magento/module-store/Model/StoreManager.php(168): Magento\Store\Model\StoreRepository->get('second?___store...')\n#1 /magento-2.2.dev/vendor/magento/module-store/App/Action/Plugin/Context.php(85): Magento\Store\Model\StoreManager->getStore('second?___store...')\n#2 /magento-2.2.dev/vendor/magento/framework/Interception/Interceptor.php(121): Magento\Store\App\Action\Plugin\Context->beforeDispatch(Object(Magento\Cms\Controller\Index\Index\Interceptor), Object(Magento\Framework\App\Request\Http))\n#3 /magento-2.2.dev/vendor/magento/framework/Interception/Interceptor.php(153): Magento\Cms\Controller\Index\Index\Interceptor->Magento\Framework\Interception\{closure}(Object(Magento\Framework\App\Request\Http))\n#4 /magento-2.2.dev/generated/code/Magento/Cms/Controller/Index/Index/Interceptor.php(26): Magento\Cms\Controller\Index\Index\Interceptor->___callPlugins('dispatch', Array, Array)\n#5 /magento-2.2.dev/vendor/magento/framework/App/FrontController.php(55): Magento\Cms\Controller\Index\Index\Interceptor->dispatch(Object(Magento\Framework\App\Request\Http))\n#6 /magento-2.2.dev/vendor/magento/framework/Interception/Interceptor.php(58): Magento\Framework\App\FrontController->dispatch(Object(Magento\Framework\App\Request\Http))\n#7 /magento-2.2.dev/vendor/magento/framework/Interception/Interceptor.php(138): Magento\Framework\App\FrontController\Interceptor->___callParent('dispatch', Array)\n#8 /magento-2.2.dev/vendor/magento/module-store/App/FrontController/Plugin/RequestPreprocessor.php(94): Magento\Framework\App\FrontController\Interceptor->Magento\Framework\Interception\{closure}(Object(Magento\Framework\App\Request\Http))\n#9 /magento-2.2.dev/vendor/magento/framework/Interception/Interceptor.php(135): Magento\Store\App\FrontController\Plugin\RequestPreprocessor->aroundDispatch(Object(Magento\Framework\App\FrontController\Interceptor), Object(Closure), Object(Magento\Framework\App\Request\Http))\n#10 /magento-2.2.dev/vendor/magento/module-page-cache/Model/App/FrontController/BuiltinPlugin.php(73): Magento\Framework\App\FrontController\Interceptor->Magento\Framework\Interception\{closure}(Object(Magento\Framework\App\Request\Http))\n#11 /magento-2.2.dev/vendor/magento/framework/Interception/Interceptor.php(135): Magento\PageCache\Model\App\FrontController\BuiltinPlugin->aroundDispatch(Object(Magento\Framework\App\FrontController\Interceptor), Object(Closure), Object(Magento\Framework\App\Request\Http))\n#12 /magento-2.2.dev/vendor/magento/framework/Interception/Interceptor.php(153): Magento\Framework\App\FrontController\Interceptor->Magento\Framework\Interception\{closure}(Object(Magento\Framework\App\Request\Http))\n#13 /magento-2.2.dev/generated/code/Magento/Framework/App/FrontController/Interceptor.php(26): Magento\Framework\App\FrontController\Interceptor->___callPlugins('dispatch', Array, NULL)\n#14 /magento-2.2.dev/vendor/magento/framework/App/Http.php(135): Magento\Framework\App\FrontController\Interceptor->dispatch(Object(Magento\Framework\App\Request\Http))\n#15 /magento-2.2.dev/vendor/magento/framework/App/Bootstrap.php(256): Magento\Framework\App\Http->launch()\n#16 /magento-2.2.dev/index.php(39): Magento\Framework\App\Bootstrap->run(Object(Magento\Framework\App\Http))\n#17 {main}","url":"/?___store=second?___store=default","script_name":"/index.php"}
