Posted this over in General/Editor but it probably needs to be here in order to fall into the right hands... Quote from old thread detailing the issue below: Well, did an inspect on the Package Manager page and one of the child pages (the HDRP page).... The Package Manager List Header shows up as: font-family: 'avalonbold', sans-serif;.... while the HDRP Header: font-family: avalon, sans-serif;. The catch is the actual full name of Avalon's bold font is avalon-bold, so its probably falling back to generic sans-serif whatever. Whereas avalon's actual name is avalon, and is an actual cursive nightmare that I must have installed for a graphic design project recently. So, looks like its actual broken and I just happen to have this one uncommon font installed to see it.
