UPDATE...
A very helpful gentleman at QB support walked me through several processes and we were able to produce a correct check stub! Still not sure what the problem is at the client location, and it will require me being there in person to correct, but the question is answered.
And for those of you wondering... or wandering... here are the items included on the vendor check stub:
Date of check, Name of vendor, Date of Bill, Type (Bill), Reference (Bill no.), Original Amount, Balance Due, Payment, Check Amount, Bank name (not sure from where tho), and a grand total.
