It's good to see you here in the Community, @mm_investments.
I'm here to share some insights regarding the description of your bank transactions and how you can correct them.
The system is dependent on the information that was sent from your financial institution. Since the description is showing as Xx Xx Xx, you can edit it after adding them to the register.
This goes the same way with those transactions that were manually recorded in QuickBooks. Just reopen the transaction and change it from there.
