What aircraft are you trying to use the flaps axis for? I have a Saitek throttle quadrant and it works just fine for the C152, TBM and Savage Grravel. I also use the flaps axis with my X52 throttle on the Flying Iron P-38 and Carenado C337. Logitech bought Saitek so unless they changed something for some reason your throttle quadrant should work for this just as well as mine
Edit: here’s a photo of my TBM setup to show how I am using it for the flap lever
