Hello,
Thanks for the information. As per the documentation provided, I realize that it is not possible to unmatch a single line from a manually matched entries.
"To remove a match, select the bank statement line, and then choose the Remove Match action. If you have matched multiple bank statement lines to a ledger entry, and need to remove one or more of the matched lines, all of the manual matches are removed for the ledger entry when you choose Remove Match."
