Safe Harbor Match Issues

Large plan filer with payroll integration to the recordkeeper. Originally safe harbor match 100% up to 5%. However, signed an amendment for 2021 plan year to change to safe harbor basic match and distributed the participant notice as such. The plan information on the recordkeeper website and materials were updated to safe harbor basic match.  This is where I get the plan without any of the knowledge of the amendment. Plan was restated later (effective date 1/1/21 signed 2022) with the prior safe harbor match 100% up to 5% and have provided the annual notices accordingly to plan sponsor to distribute to participants in 2023.  The plan sponsor never changed the safe harbor matching formula in their payroll and has been matching 100% up to 5% for 2021, 2022 and 2023. Before and after the determination period was on pay period basis. Since the restated and signed plan document matches the operation of the plan, is there anything to correct?
