Duplicated downloads after updating connection on Quicken for Mac

cabsouth

Bank names recently changed. Routing and Account numbers changed. To enable transcation downloads, I first disconnected account. Reconnected to new bank name and chose appropriate account. First download 4/17/23 worked great.

Next morning I downloaded tranactions, and many recent transactions were duplicates. What can I do to fix this and/or prevent it from recurring.

TIA😀
