Can't create sprite in Sprite Editor

When I trying to create a new sprite by clicking left mouse button its creates only green zone like child of another sprite. When I try to slice with "slice" button it did the same thing I cant move this green zone. I can move and resize blue sprite. When Im deleting blue sprite and trying to create new it make the same to another sprite. ![alt text][1] [1]: /storage/temp/167271-аннотация-2020-09-10-164736.png
