FortiEMS quarantined a file with the same checksum as a file in my allowlist

My FortiEMS has quarantined a file that has the excact same checksum as a file in my allowlist, its just the name thats different but it still got deleted from the client. But because the checksum is already listed in my allowlist i have no option to unblock the file. Has anyone an idea on why this happens and how i can unblock the file?
