Firmware will not change Steps/MM

I am using an Azteeg X3 Pro board. I have M8 Ballscrews and was setting my Steps/MM to 825. This was the same settings I used on my Azteeg X3 board but it had a stepper controller go out and I decided to go with the PRO version. No matter what value I put in for the Steps/MM in the firmware it ALWAYS moves 1.75MM at 1/8 Stepping. At 1/16 it moves .75mm instead of 1mm.

I disconnected my VIKI 2.0 display and used just software to move the axis, same result.

I checked X and Y and they are off by .25mm also. I am using M2 belt with 16 tooth spockets. I have it set at 100 steps/mm. Again, no matter what I change it to, it stay consistantly off unless I change the jumper on the board from 1/16 stepping to 1/8 then it moves 1.75 instead of .75.

Any help?

    Did you change steps in eeprom? Once uploaded these are used until you copy configuration.h settings to eeprom again using e.g.
    M502
    M500

    That was it thank you so much.

    I am using the web configuration tool. I know when I made my last firmware for the Azteeg X3 board about a year ago there was a spot to select the information about the heatbed but I am not finding that now when running thru the configuration tool. I was pretty sure it was on the same tab as the extruders.

    It still is in the Tools tab: Enable heated bed support (HAVE_HEATED_BED) must be enabled to see it.
