Can't drop a component into a drag and drop gridlayout after removing a com

Hi together,
sry for my english. be possible i didnt saw a question about the same problem.

I have a DDGridLayout with a Gridlayout in each grids. i can drag and drop the components perfectly arrounf, but the issue is, when i remove a component from my DDGridLayout “ddGridLayout.removeComponent(component);” with a custom button. I’m unable to drag and drop another Component in this empty cell, where i just removed a component.

Anyone a idea, how to handle it? Do i have to set a drop area to the empty cell again or something?
Thank all for help,
