Does this happen in all documents — even brand new documents?
Are you sure the language applied to the text (select some text and see the Language popup menu in the Character panel) is set to English?

If you want to post images, you can put them on a site like imgbb.com and then post the URL here.

What kind of output are you creating? Reflowable epub? Fixed layout epub? PDF? Something else?

It’s easy to change the hyphens throughout all the text… but you’re saying you’re getting a different kind of hyphen at the end of a line? Not the normal dash?
