How do I remove the '-' from page titles

Embarrassingly in this theme i cannot figure out how to remove the hyphen from the beginning of the page names that were imported as dummy data. I liked some of the dummy pages so i’ve customized them to suit my purpose and have renamed them accordingly but the hyphen or ‘-‘ character always remains part of the page name when viewing pages>all.

As you can see in this screen capture, the blog page appears normal but the Blog grid page has the ‘-‘ character in front of the Blog Grid name/text.

I’m sure i have been able to fix this years ago in other themes but now i’m confused, can you tell me what I’m not doing please?

Thanks very much
