Hi Stifles97,
Yes, I'm using multistore and the latest version of PS.
Now I've cleared everything in db. Afterwards I entered the attributes again but in mode 'All Stores'. Then I deactivated it in the store I don't need it. That works. Entering attributes in a selected store doesn't work quiet well.
Summarized: enter attributes in 'All Stores' and disable in store where you don't need it. Otherwise it doesn't work quiet well.
So, it works for now!
Thanks to everyone and hopefully helps this issue everyone
