Duplicated Bank Reconciliation

SUGGESTED

A recent File maintenance error check has flagged up that there is an issue with a bank reconciliation from last year. Looking into it there are 2 bank reconciliations for May 2022, both containing the exact same information & both dated & time stamped identically. A screen shot of the error is below. Oddly enough despite running previous file maintenance checks this is the 1st time its been flagged. Please can someone advise what has happened and what I can do to resolve it?
