How do I set a default bank account for checks for printing in Document Printing?

Having an issue with setting a default bank account for my customer under the Document Printing>Checks for Printing option. For some users, this is populating with their correct bank account that they wish to use as a default, for others, it is either a blank or alternate bank account. We have followed instructions to set the house bank account already as this was suggested in other Q&A sections. The strange thing is that in some databases with some users, this either saves the previous selection, or brings up the default option each time. Any help on this would be much appreciated.
