Same problem here. Working with wix has been a horrible experience so far. I can absolutely not recommend it if you are building a commercial website for your business…
A few things worth checking, since “deleted” in the font panel doesn’t always mean gone from the page:
Check every text element, not just the ones you remember editing. Hover states, mobile-only layout overrides, popups, and header/footer on other pages often keep a font alive even after you’ve swapped the “main” body copy to something else.
Check your Site Text Theme (Design > Text Theme). If the deleted font was ever set as one of the preset styles (Heading 1, Paragraph 2, etc.) and a page still uses that preset somewhere, Wix keeps loading the font to serve it, even if you can’t immediately spot where.
Publish, don’t just save. The font bundle that ships to visitors is generated at publish time. If you’re testing PageSpeed against the editor preview or a draft, you’re sometimes seeing the old bundle regardless of what you deleted.
Test the live published URL in an incognito window after publishing, so you’re not looking at a cached copy from before the change.
If it’s still loading after all that, open your browser’s Network tab, filter by “font”, and check the actual request. Sometimes it’s not your deleted font at all, it’s a font an app or embedded widget (a form, a booking widget, custom HTML) is pulling in on its own, which won’t show up in your site’s font list.
If none of that explains it, that’s worth a Wix support ticket with the PageSpeed report attached. A couple of people in this thread have hit a genuine case of a font staying cached on Wix’s side even after proper deletion, and only support can purge that.
Since this keeps coming up for different people on the same thread: if you’re auditing page speed generally and want to catch this kind of thing (unused assets, render-blocking resources, etc.) across a whole site rather than one font at a time, that’s exactly the kind of thing a Wix site audit app like Auditify is built to flag.
