Cx20/Nova transmitter modes on channel 7

The modes are showing in MP as being on channel 7 and not channel 5 when I calibrate the transmitter. How can I re-set this? The modes are not working in MP as I move the switches.
Thanks.

I just used a Nova Tx and the problem is still there so it’s not the Tx.
There has to be a setting that controls this, I’m just not finding it.

Since no one can recommend a way to repair my Cx20 flight controller, could someone recommend a replacement?

This problem has been “cured”. White wire was on the #7 pin on the FC. Moved it to the #5 pin and I now have modes on channel #5.
