Google font issues in accordion

I added the Google Font “Cinzel” (subset=latin) to my HighEnd Theme and changed every single preference under font options within the Highend Options to “Cinzel” / “latin”. The font compatibility of the Highend theme and Google font “Cinzel” has worked great until tonight when I added an accordion feature with sections and text blocks.

All sections and text blocks of the accordion are showing “Cinzel” font during the first second when it first loads, but then it immediately changes to some ordinary, standard font. This is even worse than if it initially loaded with normal font, because it shows how amateur my website is to have the font change suddenly from beautiful “Cinzel” to ugly common font.

Also, everything else on that particular page looks beautiful with “Cinzel” … except the ugly accordion section.

How do I keep it showing as “Cinzel” font all the time? Is there code I can add to the accordion section manually in the Classic Editor?

Thanks!
