Has anyone else experienced weird transactions showing up or being changed in the bank register, and you know you didn't do those?  Two examples:

• while reconciling my most recent statement, one of the transactions showed up as created in 2020.  
• As I was entering a couple of new transactions in my account today, I noticed a brand new deposit dated 1-27-22 (today is 1-31-22) from the account "Opening Balance Equity," and it shows as Reconciled (R).  

How do these things happen when I am certain I did not put them there???  (I am the only one who has access to this QBO account.)
