Presets are messing with custom.css

Hello,
I can't get rid of presets. default.css is coming back always in the new presets folder.
Because of messing with my CSS, I disable the folder, but helix generates a new one.

Here it says - it will not work! https://prnt.sc/1zx0ng0
It's not a new problem, it makes me crazy for years, but now is more aggressive with regenerating
templates/shaper_helixultimate/css/presets
As I remember, last time it was only on updates of Joomla! or HU, now I have to lose all day to make new CSS with your new rules.
So helix Ultimate, doesn't listen to custom.css completely!
