"edit form" is playing up

[sowrudy]

Hi Team, recently I notice that the edit function of my fusion 360 is playing up. When I select "edit form" (on form tab), and try to edit it, it automatically highlights/select the selection next to it  (see screenshot, as it's hard to explain). This stops me from editing anything on fusion. If this is not an error on fusion, then I must have mistakenly mess up the setting. Don't quite get why this kind of function actually exist.

Both handles highlight because both scale the selected object in the same direction. I don't see why this is a problem!
