Publish Settings File Does Not Travel

Hi, all.

It seems that some settings we make in the Publish Settings do not travel with the settings file (or anywhere else in the project files). Can that be right?

This is the situation: We use FM 2015 to save to PDF and output to .chm format.

When we generate .chm files, we need to override our H1-H4 heading formats because they are right-aligned as side heads for the PDF. We need them to be left-aligned in our online help topics.

Therefore:

1. I go to the  Publish/Settings/Edit/Style Mapping window, select one of the headings, such as H1,
2. I click the Edit Style button and select Block.
3. I set text-align to Left.
4. I save the change.
5. I put the entire working directory onto our shared drive, and my fellow tech writer copies the files to his hard drive.
6. When he generates .chm help, the left-aligned setting does not come through. The same H1-H4 are still right-aligned.

It seems impossible that the setting overrides are not stored in the settings file, but they don't seem to be. Does anyone have any suggestions as to what is going on?
