AH/Altitude indicator problem

Hello,
I have a FS202Pro. I downloaded and installed a lot of add-on airplanes and gauges. During installation I had to overwrite same files because I installed gauges for specific aircrafts. My default airplane's gauge is working fine; however, all the add-on airplane gauge is not working. Particularly altitude indicator. When I bank aircraft to left aritifical horizon moves to right. When I tried to bank right AH moves to left. It is really annonying. How to remedy this problem? Also how do you relaease tailhook from fighter jets?
This problem only applies to download aircrafts not default aircrafts from FS202pro.
I look forward solution to my problems.
Thanks and have a nice day.
