Partially failed variable rename

After having renamed a few variables of project https://snap.berkeley.edu/snapsource/snap.html#present:Username=s_federici&ProjectName=diffusione%20coronavirus-it-1
(as shown in project https://snap.berkeley.edu/snapsource/snap.html#present:Username=s_federici&ProjectName=diffusione%20coronavirus-it-2), several variables, e.g. "Infected" in sprite1, still have their old name.

  1. What browsers show this problem? Chrome

Me too! I rename and some just flat out don't rename, and the variable is lost in the categories. I can't get it back or make a new variable with the same name (it says it already exists) so I have to recover.
Good thing I saved right before I tried that.
