Linux debian 10, CPU clock stays the same, why and how to fix?

Question

linux

I changed the frequency and plans of powersave, ondemand, etc., in the utility cpupower-gui, the frequency changes everything is ok, but let's say I set the minimum frequency there to 1400 and the maximum frequency to 2200, I press apple and the frequency increases to ~ 2200 and stays at this level in any situations in any plans, in in any position, the frequency is always kept at the maximum that I set, why is that ??

That is, the behavior is as if I set the minimum frequency to 2200 and the maximum to 2200,
although the minimum is 1400

Deleted rebooted, changed plans to manual frequency does not loop so

Installed on a new one, rebooted, everything works as it should have worked.
I watched the frequencywatch grep MHz /proc/cpuinfo
