Can't save dashboard script after do Version Control

[evanderbird]

How to reproduce
save progress to Version Control like usual

after successfully saved, close this and back again to dashboard

then I continue working, edit some action button script

save everything by pres save button like usual, back to dashboard

when I try run the function, I see nothing changed to my function even I save all my progress? Then I back to see my codes on that place again (java script editor like picture before) and my changes all disapear. Even I try edit & save again that actualy didnt saved.

Always happen if edit the codes after I saving to Version Control.
I can do reload my page to get it working again. But when I forgot about reload page after save to Version Control, that is a pain.
