Hi all,
my requirement is:
I have a SharePoint List with tasks and responsibilities for different Groups.
I only want specific people from one Group to edit their "own" tasks and responsibilities.
What i tried so far:

But i have this weird problem:
For example i want to edit a Operations Tasks and i am in the Operations group . First Time i click edit the form is on viewform when i press cancel and edit again it works. But now if i go to "Qualität" and i am not in the group, the first time i click on edit i can edit it. If i press cancel and edit again its on viewform and how it should be.
