When I create a foliage actor (Basic Trees) I have the ability to place the actors throughout the level but when I shift click to delete one or more of the trees Unreal engine crashes with the following error: Assertion failed: RemoveCount == 1 [File:D:\build++UE5\Sync\Engine\Source\Runtime\Engine\Public\Instances\InstancedPlacementHash.h] [Line: 98]
The rest of the error proceeds as follows:

If anyone could give me any insight into what is going on I would very much appreciate it. As a new developer I could just be overlooking something very simple. Thanks in advance for any answers!
