EXT Level Button stuck. error

[Foxlees]

I have an error message on my Dynon HDX EXT Level Button stuck, I do not have an Autopilot, level button or anything connected to the D37 Pin 26 through 28 for an external level button these connections to both displays are not wired. I did do some reading about diodes being required when connecting a level button to both displays, however since I do not have anuthing connected, to stop thios message from appearing on bootup, do I need to hold Pin 28 High or low through a resister, is the issue due to it floating.
thanks
in advance
Regards
Simon

Sounds like you have a short somewhere. Did you physically check the wires and connector pins?
