'no changes added to commit' when syncing an experiment

Hi!

Every time I try to update the experiment through Psychopy an error occurs:

Changes not staged for commit:
modified: “\342\200\217\342\200\217Xp2_-legacy-browsers.js”
modified: “\342\200\217\342\200\217Xp2_.js”

no changes added to commit

And to fix it I have to delete the folder (git) and do everything again.

Is there a solution to this?
