Thanks for the quick reply.
Yes, I am clicking OK, and no, I am not clicking on another saved view which would override the custom view settings I just created. So that's not it.
I did just check the TW settings, I am set as a Lead Architect and I have all the permissions. So that's not it.
I opened that file as a standalone PLN and the same problem...
I then closed the file and created a new blank file, and the same problem.
I then opened up another V18 file, same problem.
What I did notice is that the change is visible IN the pen set settings, and it's visible in the settings for the individual element. It's just not updating in the model until I close and open the file!
