Older paragraph tags don't display in .pdf file

Here is another example:  Cell Heading paragraph tags do not appear in PDF, but appear in FM file fine.
The Paragraph designer:

Displays in FM file:

But not in the PDF.

Does anyone have a clue what is causing this?

The FM version is the newest one.

However, it's unclear, what you mean with:

"I created a tag in an older version of FrameMaker."

Did you create a paragraph tag with an old version and copied it into the file with the new version? How?

How did you create the PDF?

Save as PDF? (Is the option "Use Acrobat Distiller for PDF generation" in the Publish pod activated?)

Or did you print to a PostScript file? Which printer?

Is the paragraph on the body page or on the master page? Does it have a special color? Do you use the color views (View | Color | Views)?

Is this autonumbering?

Or is this an image and not regular text?

Is there anything on top of this paragraph which is not visible in FrameMaker, but hides text in a PDF?

Generally FrameMaker prints whatever is on the page. Therefore there must be something special.

I stuck your screenshots back into your message - don't use attachments.
Are you expecting to see that "NTP" text appear in the PDF? How is it defined? And what version of FM  & what method of PDF creation are you using?

How do I fix this issue?
