Change Table of Contents Page Title style in RH 11

I want to change the style of Table of Contents Page Title for Printed Documentation. I would like it to be left justified.

I have added the style to the CSS using the CSS Editor - no luck. First, the Table of Contents Page Title style does not even appear in the CSS Editor. So, I added a style called "TOC" and then changed the existing "Table of Contents Page Title" style to "TOC" in the Style Mapping.dot file. Tried to re-generate the printed doc and it still inserts the original "Table of Contents Page Title" style and does not apply the "TOC" style to the page title.

I simply want the table of contents title to be left-justified, but I cannot seem to get it to recognize this style change.

Any suggestions? Ready to tear my hair out! We have about 50 guides to generate and I would rather not have to manually fix in each Word doc.
