Blocks : All variables are marked as non-existent

Describe your issue

Everytime i go to another screen, image , all the variables blocks (except for initializations) are marked with a red cross : image

A click on any block instantly makes them disappear.

Steps to reproduce the issue

I’m using firefox.
Use firefox, go to the block view, change screen (go to a screen with variables), and they are all marked as error. Just click on any block to make them disappear.

Does this happen in other browsers?
Can you check if this happens in App Inventor?
Does it only happen on one project or all of them?

Yes I also have this bug in variables I am using Chrome

I just tested this and couldn’t seem to reproduce it. Could you provide the specific steps you are taking for it to happen?

I closed the project to re-open it in chrome, but now i can’t reproduce it anywhere !

Maybe it was just a loading error which appeared once :thinking:
Let us know if it happens again

There is a bug, it is wierd however it is not fatal

I last encountered this error today when dragging a new block onto the blocks area.
