I added Page numbering Roman 1, Roman 2, Roman 3 (Page number menu), same results.

Number displays correctly as XII, in TOC-s (I have 2), it is "12".

This is a nagging problem as publishing approaching.

Thanks.

P.S. The sections are OK.

Section 1: Title pages - no numbering

Section 2: Chapters TOC (Heading1) - no numbering

Section 3: TOC (3-level) - Roman numbering starts
INTRODUCTION - Roman number XII

Section 4: Book pages - regular numbering start at 1
