Move blocked

[Pejamide]

In the new version 2.10 it appears, that I cannot move an item within an image via the first menu 'Move'. For example, I created an new item in lettres and I want to move that item to another position in the same image, but it is not possible because of the combination of three signs: plus, prohibition sign and square.

I am using the GIMP version 2.10 running under Windows 10. In the older versions I am able to move an item.

What to do now?
