Safari Not Displaying Website Fonts Correctly on macOS

Hi everyone, I'm having an issue with Safari not rendering the fonts correctly on certain websites, particularly on site such as Sincere Mechanic. I’m using a MacBook Air running macOS Ventura, and the Safari version is 17.1. When I view Sincere Mechanic or other sites with custom fonts, Safari sometimes displays a generic font instead. This issue doesn’t seem to happen on Chrome or Firefox, so I suspect it’s specific to Safari. I’ve already tried clearing the cache and disabling extensions, but the problem persists.

Does anyone have advice on how to fix this? Could this be a compatibility issue, or is there a setting I might be missing?
