What would cause the RMB menu for a symbol to change? I suddenly have a smaller/abbreviated menu for a bunch of symbols on a page (but not all symbols on this page). I'm trying to edit the Device Properties, but that's not an option anymore on this menu. I know it worked previously because I've made recent edits to these symbols on this page.
If I add a new instance of the same symbol to the page the RMB menu is as expected.
