All pages show file name not Title - Rh2022 Frameless output - tried RH-11277 resolution

This seems related to RH-11277  but not the same. On every page the Title is displayed when I preview the page. When I build the output the file name is shown on every page. The file name is without the .htm which is odd. See image below.

I have taken the following steps:

• Checked all files in Contents folder for invalid file names and corrected some. Mostly images with spaces in the name. One topic file name had a special character. ( I was hoping that was the issue but fixing it changed nothing)
• Opened properties of all topic pages and verified title is set correctly and clicked Apply.
• Cleaned up and reviewed everything I can think of.
• Reapplied the Title field to the Topic Layout header.

While doing clean up Rh corrupted my CSS file by trying to make it a topic page and adding XML and converting special characters to esc sequences. I only add this info in case it is revealing of some other issue.

(The upper case is due to CSS transform.)

Thanks for your thoughts on this frustrating problem.
