KH120 II + MA-1 room alignment

[TimnEst]

Hello everyone! I'm currently trying to make some measurements with MA-1 for newly bought KH120 II monitors, but after correction one of my monitors (the left monitor) is for some reason slightly louder than the other, and when I apply the backplate settings everything goes back to the default settings before the correction and the sound is sort of more in the middle and there is no difference in volume.

When I switch the monitors, so that the less loud (left) one is on the right, the sound is louder on the right. The settings on the backplate are equal between them.

My room is 6x3m2 and the distance from my monitors to the walls is currently not equal and there is nothing I can do with it, the room is also slightly treated.
Maybe the room acoustics somehow affect it/I somehow do the measurements with the MA-1 incorrectly or the hardware (monitors themselves, my audio interface/wires) is the problem.
I also attach the screenshots of my audio interface setup and the final measurements from my room

What are you trying to achieve? Of course MA 1 will apply different settings to each speaker if the selected setup is stereo, that's the whole point.

slightly louder than the other

"Slightly louder" is how much exactly? How the speakers are placed in your room? How are they connected to the system?

The settings on the backplate are equal between them.

The backplate settings have no effect when the Control switch is set to "Network" position, and all acoustical controls are applied through the MA 1 software. The moment you move the Control switch to "Local" position, the MA 1 settings get overridden by the backplate settings, and room correction is no longer active.

Have you read the manuals (both for the KH 120 II and for the MA 1)?

the distance from my monitors to the walls is currently not equal and there is nothing I can do with it

I think we have the answer.

Maybe the room acoustics somehow affect it

That's the whole point of room correction.

I somehow do the measurements with the MA-1 incorrectly

Could be. At least when done right, the alignment should not introduce a shift of balance at the main listening position.

or the hardware (monitors themselves, my audio interface/wires) is the problem.

Perhaps. Too bad you didn't provide much information on your setup and your procedure, so at this point there's a lot of guessing.
