There are many possibilities. Some of the more common ones in your situation are:
1. VTF too light causing mis-track. Solution: increase VTF but don't go over maximum according to spec.
2. Dirty stylus. Solution: clean stylus and your record. Dirts on the stylus are from the record. You need to clean that too.
3. Damaged record. No solution, try a different record.
4. Overhang alignment setup wrong. Solution: get a protractor for the length of your arm. Realign cartridge.
5. Too much capacitor loading for MM cartridge. Solution: reduce capacitor loading of your preamp. If it doesn't have that adjustment, there isn't much you can do.
6. It is how the cartridge sounds. No solution except get a different cartridge.
