Ok, which filament do you use? You used Generic PLA profile and standard print profile to slice (as I can see in 3mf) and it seems that printer/filament max flow is to fast for this filament.
I would choose ‘high quality’ print settings in slicer and create filament profile for the filaments you use because the filament print setting are not OK for both filaments as I see from picture.
You may use this thread to see how you can get better settings for you filament.
p.s.: I would use as infill adaptive cubic, it prints faster at higher strength than cubic!
