Why are commands grayed out in the shortcut menu when they are still available in the quick access toolbar?
this example is how the custom symbol command is grayed out on my shortcut menu but not on my quick access toolbar.
Changing tabs does make this option available.
My question is why would it be available in the quick access toolbar regardless of the active tab, but then be grayed out in the RMB menu when not in a specific tab.
I have seen a similar problem with icon Relation in drawing.
It worked only in the tab Tools.
Looks like there is some other issue in your case.
