The attached 2 minute video documents the problem. When I switch from JavaScript to Blocks the editor turns all my numbers to nulls. I first created the program in Blocks but a few days ago this behavior started. I opened old programs and experience the same problem – but not always. I have used different computers, even an iPad. Same problem. I wrote a small program to illustrate the behavior, which it did, but after a few more changes the behavior went away. Now I am stumped. Any help very much appreciated.
