Intuit still needs to fix this bug in their Quickbooks Online software. My workaround is not a fix, but a temporary solution to get you by. If you remove the Name and Company Name from the Mailing Address field leaving only have the address and city, state and zip code. I am referring to the paid bill where in Quickbooks Online has the options to Print Check, View/Edit, Delete or Void that record. If you choose the View/Edit record then you will see the Mailing Address field (see attachment)
