cannot get preview or print after adding addt'l columns even with highlighted print area

I first previewed and printed A1 - E24
then added data in F4-F8 and saved
I highlighted for printing and preview from A1 - F24 but it doesn’t preview or print anything more than the first A1 - E24. There must be an easy fix!
I am not proficient at LibreOffice, sad to say…
Thanks for any help.

What do you mean by I highlighted for printing? (check what’s in Format -> Print Ranges -> Edit, keep in mind that additional columns may appear on a second print page, if they don’t fit onto the first page and check Format -> Page Style (or Page) -> Tab: Sheet for setting the details of your printout)
