Sugar 5GA

If i try to rename some fields in the subpanels first it looks fine if i save them , but if i come back later everything is back to as it was.save and deploy does not work at all sets everything back what i changed.

As i do it:
login as ADMIN

Go to admin in top menu....
scroll down and select Studio...
choose in left site tree folders Accounts.... (example)
then choose subpanels....
then choose Contacts....(example)
then choose Name to edit...... (example)
change in to "what ever".... (example)
then click on save in right table....
The it shows in the middle the changes correct

but if i go out and come back a few sec. or min. later the change are gone

Any one an idea???

thanks a lot for any idea that solving this problem

greetings
