Fonts not previewing in Adobe fonts, showing as sans serif

I've had this happen before, searching for the right font in adobe fonts and some fonts show an example and some do not - some just show example text in a sans serif font, and even if I click on the font to view the font family, all I see is a sans serif font. Is this a setting I need to change? In scrolling through the list of fonts I do see the sample blocks of how fonts are used, but again - not all fonts.  Right now searching brush scripts, I do not see an example of Viktor, but do see examples of Kestrel and Salamat.
