You didn't indicate whether you have the advice 1 section repeated on your check spec, or if you have both advice 1 and advice 2 selected. If you get the column headings on one advice but not the other, I presume that the latter case is the situation.

If indeed you have both advice 1 and advice 2 selected to print on your check, then you have to ensure that the column headings are also entered into the Advice 2 Header section. Whatever you have in the first advice sections will have no influence in the second advice sections, and vice versa.

Either copy and paste the desired information from the advice 1 header to the advice 2 header, or insert them manually.
