Hey, I know this is old, but I just had a match where I was playing as Moira, and it was locked into "I'm with you" even though I wasn't looking at anyone. I used to be able to to look straight down to get "Group up" because I couldn't figure out why it would say "I'm with you", but now even looking straight down, it will say "I'm with you". I checked, and I have contextual comms wheel turned off. I even checked Moira specifically because I have a few settings customized. But contextual comms was off for her too. So I have no idea what the problem is, and that's very annoying.
Edit: Is it some sort of glitch with "Enable Automatic Need Help" on? That seems to be on by default under Advanced below contextual comms wheel.
I don't have a good explanation for why this would only happen with Moira. If you have Contextual Comms Wheel off, you shouldn't have had to look down to get a different response. Enable Automatic Need Help is a feature that will cause your hero to call for help when you ping if an enemy is attacking you at very close range and your ping hit no targets.
