I think I have the same problem with C4FM to DMR as Paul.
I use a Yaesu FT-5D also, created a connector with quick setup, can listen to the traffic in the talkgroup and also see everything scrolling in the status window.
When I press PTT on the radio, I see my transmission, but with the TO ALL entry in the status window at the top, instead of the destination talkgroup entry as with other traffic in the status window.
Because I am currently on the road, I cannot try other cross modes. Your tip with "Route cross mode calls to ID" didn't help, the C4FM notes you mentioned didn't help either...
