I'm wondering if anyone else has this issue, that's been happening since this week.  When I enter a check, or a journal entry and categorize it as Accounts Payable, only Customers appear - no Vendors.  When I contacted support, the rep didn't understand that Accounts Payable = Vendors and Accounts Receivable = Customers.  They said they would look into my 'suggestion'.  It happens on my QB Online versions Advanced and Plus. 

Hoping others with this issue have better luck with their support reps.
