Plunkr Case (Bug Reports)
Splitters panels are multiplying when using nested ngTemplates.
I have I quite complex scrollPanel I wanted to insert into the splitter. It includes a few form-elements, two p-tables and a ngif loading ngtemplate.
When calling the site there are more than 2 panels, the scrollPanel is in two of them, one is the loading-ngtemplate and one is my right-side-splitter-element.

I tried to make a simple example of the problem. It happens when you move the splitter.

Current behavior
Many panels are created and in my place the change of the size is not working.

Expected behavior
Only the two panels.

You need to use splitter inside of splitter. Check nested splitter.

No I don't want nested splitter. I just want 1 splitter with a right and a left side.
It just creates more panels and I don't know why!

Did you try a single child of <ng-template>?

<ng-template>
    <div>
        <!-- your original content here -->
    </div>
</ng-template>
