I have a multiple choices column that I editor users should not be able to modify or add their own choices. But if I open the Column view, I can enter a new choice in the list and save it. I get the msg saying that I don’t have the right to add it… but it is added.
Then I can go on that column and use that choice.
Note that this new choice doesn’t show to other users, and it dissapear if I change page.
It is a small bug… bug could probably cause some pain if there are other columns that depends on the value from this column.
