top layer underextrusion

I have a strange issue,
I just recently setup a new printer vc3.1 300 which is running klipper.
I have no expierence using the klipper system, my other printers use duet boards.
I also decided to start using orcaslicer for this printer just to see how i would like it.

Everything is printing pretty well at the moment I must say, until I get to the top layers, the extrusion just seems to be way to less, even when running the flow rate calibration from orca slicer the issue seems to remain the exact same across all of the different samples.

I hope someone can help me out here, am I doing something wrong in the orcaslicer settings?
I'm using the default slicer profiles that come with orcaslicer.

I'm running a rapido with bondtech cht nozzle (0.4) and a mellow vz hextrudort
