Data Integrity - E: The Year/Period of the latest activity [201406] is not consistent with those maintained in payments [201405]. IDCUST:[xxxx]

IN our A/R data integrity reports, I see lots of entries stating 

E: The Year/Period of the latest activity [201406] is not consistent with those maintained in payments [201405].
IDCUST:[ARISEH]

Do these need to be fixed / how?  - or if it should be ignored.
