Nozzle not touching siliconbrush

Noob here and only had my printer for a month.
When the nozzle is supposed to be cleaning against the siliconbrush it doesn’t touch it. It makes the measurements on both sides but then it seems to raise so the nozzle are above the brush. Is it supposed to be like that?
How to adjust if not. (Sometimes there are old fila on the nozzle after the “cleaning”.)
Cheers
