Drawing one new rectangle - all other rectangles change their colour

since yesterday I've got a very big problem with my lectora-project. When I draw a new rectangle which is green, all my other rectangles that had been yellow til then, also become green.

When I select "undo" my new drawn rectangle is away, but the other rectangles stay green nevertheless. Even after closing lectora without saving the changes and then reloading the document, the fault remains.

Same thing when I draw new arrows. All rectangles change their style and become an arrow.

Has anyone an idea what I could have done wrong?
