Need help in configuration of webdriverio v8 with multiple-html-cucumber-reporter

[Sweetie7]

I have used package - wdio-cucumberjs-json-reporter, to create json file. And then used package-multiple-cucumber-html-reporter to create html report using that json file.
But the issue is when I execute multiple case with maxInstance as 1 (means it executes one by one), then its not able able to merge all json. Hence, I see just one feature in the report and not multiple feature.

Please advice.
