I did a search in the forums and didn’t find my exact problem, so I was hoping someone can chime in with a possible solution.
My T.flight hotas is recognized and mappings work correctly except for Elevator and Ailerons. Both show nothing (see first pic) when I enter controls and then when I move them they appear and do the correct movement. exit controls into aircraft mode both do not work (just move slightly and pop back). when I go back into controls they are blank again until I move them.
I unplugged the USB, uninstalled Tflight driver and reinstalled, calibrated but nothing seems to help.

Hmmm not too sure without looking at my settings. I’m away at the moment.
Just looking at your image, do you have your yoke plugged in at the same time? Could it be your other peripherals not playing nice together?
I do have my CH yoke and rudders plugged in. I will give it a go with disconnecting them the next time I get on. Thanks for the reply. I would much rather fly the Iris PC-21 with my stick versus the yoke 
, first Add on and I am impressed.
Looked at my settings they look the same as yours. But, My elevator reverse axis button is not checked. As well I don’t have my rudder bound to the stick, as I use rudder pedals and have the joystick locked with the small lock screw on the side of the shaft.
Only thing I can think of is you’re trying to save from the default profile. Make a new profile “profile 1” lets say, and try to make your changes, then apply and save to that new profile. Hopefully then your settings will “stick.”

both pics look right, you wont see any ‘white line’ until you actually move the device
all of those settings show the Axis they are Mapped to in your pics just as they should
i have rudder pedals so twist is locked and i dont add any drivers,
i always just used the plug and play driver that comes with windows
i also have both a yoke and hotas plugged in together, that shouldnt hurt anything but …
i do notice if your ingame and try to ‘swap’ you may have to jiggle the controller to ‘wake it up’ so to speak
i ended up getting a powered hub (Highly suggested for this many powered usb devices) for them that has switches, so i can turn them on/off easily now
I tried this unfortunately it did not work 
I actually have a this plugged into a powered USB card, This is a Hotas I purchased back in 2012 it has served me well, might be time to upgrade. Any suggestions ?
