Issue with custom fonts

Thank you for this plugin, it’s the first one I’ve tried that drastically improved my websites scores on pagespeed.web.dev

I can only see one issue. I’m using Woolentor – Universal Product Layout and the custom font I’ve set changes to Sans-serif after selecting “Optimize CSS Loading“.

Here is a page you can see this issue – http://www.wondertree.co.za/sapele-veneer-connectors/

If you “Inspect element” on the title of a product, you will see that the font family is set to “font-family: var( –e-global-typography-primary-font-family ), Sans-serif;”, if you scroll down a bit, you will see that the font I set is “font-family: ‘Poppins’,sans-serif;”.

Do you have any recommendation on how I can fix this? Beside this issue, everything is working great.

Thank you.
