(I have been not changing code and login for a long time to App Inventor.)
Today I have only sorted by category, expanded all blocks and probably arranged horizontally to download all blocks from screen1 as image,
and I see 44 warnings in red color.
I have 2 screens and I've found that blocks from screen2 I can see in screen1.
I can not now undo. Please help.
You probably had blocks from screen 2 in your backpack. You accidentally pasted them onto the screen1.
Try using the undo command from the context menu.

You are right. Backpack is empty. I can not undo. I will find last aia and import.
Thank You Patryk.
