What is the reason for the volume increase for CUT of EQ?

Hi. I am using Cubase version 9.5.
I did a low cut snare sauce during my work today.
I see a lot of increase in level.
I have attached a photograph.

The level goes up from the moment you turn on the low cut filter.
The more you sharpen it, the higher it goes.
The level goes up when the high cut is done.
Cutting more than half will lower the level.
This level is lowered only if you have to shave the power of the sound.
The same is true with other eq plugins.
I wonder what is the problem and whether others have this problem.
I would really appreciate it if you could give us a solution.
I do a low cut to secure the headroom.
The level is so high that it feels like a loss.
