RH 2020: How can I find and fix errors mentioned in my log file of a Word printed output?
I'm re-trialing RH 2020, Update 7.
I have a Word document I generated. According to RH, the output generates successfully. But when I open the .docx file, I get this "Word found unreadable content..." message:

If I click Yes, I can then see the contents inside Word. The filename is named Document1. From a cursory view of the document, it looks like all the expected topics are there.
Curiously, at the end of the log, there are some validation errors:
Merging 10_view_topics/Viewing_Path_Lines.htm...
Merging 10_view_topics/Viewing_CAD_Import_History.htm...
Converting mergedHTML.htm

From the message, "invalid value disc", it appears that there may be some bad numbering or bullets in some HTML code or something, but the log is not helpful in determining what topic or topics has the issue.
Does anyone know what this means?
And, most imporantly, how can I find where and what to fix exactly?
