Resizing TableArrangement creates zombie components

I had a two column TableArrangement with 7 rows, 6 of them filled with components. After accidentally resizing the arrangement to 5 rows and subsequently extending it back to 6 rows the components from the original 6th row can’t be found anymore in the Viewer but still exist under Components. Is there a way to revive them? If I’d simply delete them all code associated would be deleted too.
