Assuming you are wet sanding I would suggest the pad has got too dry … it can happen quickly and you then have a blob of compacted material on the pad … this is probably what the scratch is from
You will always get some marks but further sanding removes them … with paint you need a lot of care all the way through.
As suggested probably better starting at 1500 to 2000g using a specific auto finishing disc and lots of water… thoroughly wash and dry between grades
