CAPSMAN - 90% CAPs get 2422 in auto channel

I am having an issue where I have a building of 149 waps controlled by CAPSMAN and the moment I set their channels to auto they tend to use 2422 channel causing lots of noise to each other.
If I do a wireless scan from one of them they get at least 10 nearby waps all with 2422. I am using the latese 6.38.5 version to both the controller and all the waps.

If I remove the CAP from the wap and enable the wifi directly with auto channel it chooses other frequensies immediately from the crowsdy 2422. I enable CAP and I end again to 2422

Any help would be appreciated

<up this just to follow, i have the same problem. I’ve set a “channel” config with 3 channels frequency “1, 6, 11” but my 2 CAPS (a cAP and a wAP) sets both channel 11, even they are at 1mt at distance.
