Some font selectors working, others not

I have two font selectors, one for the post titles and one for the side bar titles, both used to work, but now the widget title selector is not working.

Perhaps related, the font changes which add google fonts to my posts have stopped working. I can see the fonts in the editor, but not when the post is live.

The problem occurs in both Chrome and Firefox.

I recently added Jet Pack Boost, I also use Wp- Optimize and Fastest Cache, as well as Surpreme Google Fonts to add the fonts to the MCE editor in classic gutenburg blocks.

I have tried resetting all my font controls and reinstalling Easy Google Fonts. The font control shows up in inspect elements, but for some reason the Entry Title control works but the SideBar h3 control does not.

Any help with this issue would be appreciated.
