I am unable to access the properties of a legend after importing an ArcMap (10.5) layout into a Pro (2.3.2) layout. I deleted the old legend associated with the ArcMap Document and added a brand new one. I can see my layers but when I right-click to access the properties nothing comes up. I can only edit the formatting (even with that, I can't access any further functions for Text Symbol or Symbol by clicking the arrow on the bottom-right). I'm assuming this may be due to the fact that it was imported from ArcMap....seems like buggy behavior.
