Hi Newtmich,
Interesting, never had that, even I have run into some stuff that I would call User Error (mine in this case).
So, I tried to disable the option for the pin, and the only one I have found so far is given when the Editor Window, where the image is located, is not active. Click on the top bar to bring it back active.
In my example the line and grid are grayed out as well as option. Which means that would be an indicator for that case.
What ever happens, is it not working in a fresh started app as well?
BTW, there is always the option to set ONE pin, if done then the delete is available—except in your case, perhaps there are other options to fail, which I don’t know yet.
Do you mind to share that file? With a small jpg of your image?
Edit, I found another option, if the Attribute Manager is locked (to keep the current content) and when then the CC tag is deselected, it is in-active completely as well. Similar to that if it is on layer and this layer is locked. Either way, if the circle in the scene is not selected, the function is not available/edit
All the best
Sassi
P.S.: if nothing helps so far, perhaps that is a case for the support!
