I am working on a project. but now I import a screen from another Kodular project. but due to not an extension called expandable-view by Sumit I was unable to work on that project. and unable to delete any extension also. I imported the expandable-view by sumit extension it is not working. i think due to its version error.
Export your aia. Open it is zip viewer and manually delete unwanted extension or unwanted screen .scm and .bk files. Save and import again.
I help you to fix this
