I think that google is abbreviating the word ‘Company’ to ‘Co.’ in search results. If you search for ‘Pop Trading Company’, one of the sitelinks it produces under the main result is for the webshop, and it uses the title ‘Pop Trading Co.’.
Unless I have missed something, no where on the main website (https://poptradingcompany.com/) or webshop (https://webshop.poptradingcompany.com/) is Company shortened to Co.
I have tried Screaming Frog to crawl the site, and explored Search Console for an answer, but have so far been unable. Is there a way to get a handle on this?
