We have this same issue of Return setting showing as all uppercase but preview of return is mixed case.  This is a known issue with Lacerte as I have discussed this with them over the past two months.  Here is what happens... When you E-File a return, this changes everything so the view is now mixed case even though the options say uppercase.  If you exit the program and go back in, the view will be back to all uppercase.

I have not tried to print when it does this as I assumed it would print how it was shown.  I will try that.

I know they have a case on this issue.
