OSD not working on walksnail

I am using the fettec g4 1.7 with the newest kiss firmware, and I’m using the walksnail avatar vtx but can get my OSD to show up on my screen, I am using RX 4 and TX 4 and bridged the osd pads on the flight controller, I’ve tried every option in the serial 4 drop down menu, what am I doing wrong  

(when I’m using fettec alpha firmware the OSD works fine, so it has to be an issue with kiss)
