The range of a hyperlink is controlled by any changes in the formatting surrounding the marker insertion point. If there are NO changes in the neighbourhood of your marker, then FM will use the entire paragraph. If you apply a character tag around the text that holds the marker, then the hypertext link is limited to the extent of the applied character tag.
In your case, you should create a character tag (e.g. called Hypertext) with some different attributes (e.g. blue colour and/or underlined?) than the typical paragraph text and apply the tag to those few words. This will limit the hypertext zone and will help the users see where the link is located.

My experience is that different attributes are not strictly necessary.
An otherwise As-Is Character Format will do (in cases where you
need that, possibly URLs in print editions of documents).

That's the key contribution of the Ch Fmt.

Also true where needed.

Surely the point of a hyperlink is, erm, to provide a clickable link for online use? in which case it would seem only fair to the reader to give some teeny indication of which words are clickable and which are not. Of course, I suppose OP could be including verbatim URLs for readers to copy by hand from paper to browser, and intending to track them in the .fm source …
The intriguing bit of the question, for me, is why the same file behaves differently in Terri's installation and in others.
I followed your advice and it worked. I had applied a character tag but in the wrong order.

Sure, but various scenarios require that they be "silent". For example, I'm working on a reference manual in which almost all of the topic-specific terminology appears in a Glossary, and every use of each term is actually an Xref-by-paratext to the run-in lead para of that Glossary entry. The body text would be a visual overload if all such linked content were set-off in the usual fashion. Plus, the typical reader will only click a given term once or twice until they learn what it means, after which they don't want to see the link decorations.

The PDF reader or HTML browser does that for you on silent links. It changes the default mouse sprite to a finger.
Good points … context explains a lot, as always!
