Unable to edit non-uniformly scaled block instances

I want to add the shape on the right to the block on the left - do I need to remove all of the blocks whose scale I’ve changed in order to do it?

Hello- there is no way to know what you are referring to in the image - please post a file with just the objects you are asking about, and a clear explanation of what you would like to do.

I did it just by selecting the block instead of block editor :heart:
