og and twitter :title are duplicating the title when sharing

For https://chicago.inkworkdirectory.com

When sharing to fb or twitter, the site name (“Inkwork Directory // Chicago”) is displayed twice in the title.

ex: Home | Inkwork Directory // Chicago | Inkwork Directory // Chicago

Looking at the meta tags, I can see that in these two (but nowhere else):

<meta property=’og:title’ content=’Home | Inkwork Directory // Chicago | Inkwork Directory // Chicago’ />

<meta property=’twitter:title’ content=’Home | Inkwork Directory // Chicago | Inkwork Directory // Chicago’ />

I’ve looked through the Rank Math Titles & Meta settings, but nothing looks abnormal there. Editing the settings on the Home Page looks normal there too, even on the Preview Snippet Editor on that page for the Social tab shows it as just “Home | Inkwork Directory // Chicago”

Cache is disabled to avoid any testing issues.

Any thoughts on what else it might be or where I could check? I used another SEO plugin or two before settling on RankMath, could it just be a db value that isn’t updating properly that needs to be manually changed until you can get a fix in? I’m a web developer, so I’m happy to assist in any way possible.

Thanks!
