EOS 7D Mark II - AF-ON button changes shutter speed

[Croczor]

Hello.
In my 7d Mark II i use the af-on back button to auto focus, but it changes my shutter speed, it happen in all the modes (Av, Tv or M), in Manual i set the shutter speed to 1/400 and when i use the Af-On back button the speed changes to 1/2500 all the time.

Any one can help me understand why and what i must do to that stop happening?

Crocker,

I've never heard of that before.

Is it possible that you still have your AF-ON button tied to metering in your Custom Controls menu?
