When editing a feature, I usually can only select one face, profile, ... and have to clock "ok" and re-edit the feature to choose more even though the focus in the edit window is still on the "Profile" selection.
For example create a sketch with three rectangles. Stop the sketching and extrude one of those rectangles. Press Ok to finish the extrusion.
Now try to edit the just created feature and add the two other rectangles to the extrusion. Fusion360 allows you to select or deselect one, but then only allows you to change the dimension anymore even though the "Profile" selector still has focus (is marked blue in the edit window).
