I don't know if this will help, but I think the auto match behaviour is caused by the application looking for matches of exact dollar amounts among unreconciled transactions. I found that as soon as I reconciled my accounts, the problem went away. I also found that by clearing (checking) the transaction that was paired with the auto match entry (just click on "add more details" in the drop down box to see the transaction), I could remove it from auto match status and restore it to "review" or "change" status.
