How did a reinvested dividend also get added to a savings account

I was checking and updating my accounts earlier and found that I somehow had $2721.12 extra in my Capital One account. It was showing 2 reinvested dividends of $1360.56 each (duplicate transactions). I did have a reinvested dividend of $1360.56 in my Fidelity IRA account, this is correct and the only transaction. I had updated last night as well and my balances matched my other software program. How did this Fidelity transaction now get added to my Capital One account twice this morning? I do have the latest update to my Quicken 2019 for windows.
