Draggable element in repeating group not completely disappearing

Hi,
I’m using the draggable elements plugin and I have a drag/drop group in a repeating group (the part that I am dragging). As you can see in the gif below, the row doesn’t disappear. It still stays there. If you look carefully, you’ll notice that as soon as I release the drag/drop area, the numbers change to some other numbers which is strange.
Repeating group bug

The RG on the left has a filter on it to filter out all values that have “sorted=yes”. The workflow logic is that when the drag/drop group is released, the “sorted” field value is changed to “yes” so this value should no longer appear in the list. You can also see the number at the top “Ungrouped keywords” decreasing, so I know my logic is correct.

Anyone know how to clear the row that was just dropped? I have tried adding some actions to the workflow to clear the list in the RG, set the RG to have a list of no items and then display a list and also resetting the parent group. None of that worked.

Any ideas would be much appreciated.
Thanks
Paul
