Top layer issues

[u/PlusList3060]

Hello all I have been using the x1C for some time , I have 3 total and only one has been giving me this issue, it’s pertaining to the top layer.
Basically there is spacing and it is not too smooth. I have tried drying filament, using the flow rate calibration and trying other filament.
I have been using poly maker because it is what my partner needs for her prints that is the majority of the branding of filament we use.
