Can't order wingmen with second PTT behaviour

[VC]

Based on advice from another thread, I tried the second option under the "special" settings tab for how the PTT buttons behave. So far so good. I hit "/" then the PTT and I get the radio menu for that radio. I can talk to AWACS fine but somehow wingmen ignore me on the same frequency. If I go select the first option from the Special tab, I get the radio menu as soon as I press PTT and wingmen respond through there. Any ideas what I'm doing wrong?
