Brushes behave on my mesh weak and with low detail, why?

Hi there,

i have a strange problem. i have a character mesh.
brushes behave on this character oddly. the clay buildup is slow and creates very blurry
results on it.

i added a second geometry ( sphere ) with a similar polygonal density as the character.
the buildup brush works correctly on this sphere.

addition:
-all brushes work slower and weaker on the character model
-i am sculpting with my mouse

does anyone know, whats causing this behaviour?

here is the ztl file:

Converting it to “make polymesh 3d” and then subdividing again, fixed the problem, but why?
do i always need to convert a mesh to polymesh3d after using zremesher?

kind regards

freeze subdivision was active.
that was causing the trouble.
