Character Ground Collision Offset?

Hi,

I need help with collison on my maps.

So technically, I have custom character, and the collision worked fine, but when I created two more maps, the collision is off on both maps. On new maps, my charater walks above the landscape, like not insanely high, but visibly higher than on original map.
I tried changing the collision capsule (character component) height, and it sorted the probem in one of the maps, the character walks on the ground but then when jumps the head goes through the ceiling, and also other maps the character sinks in the ground, so that is not a solution.

How can I adapt the character to walk ono any ground - no matter of position in the world without issues?

Thanks a ton!
