Font on buttons not working?

Hi everyone,

I'm having an issue where the font on the button blocks are reverting to a different font, even though I have specified something different in the site style.

I did recently put some custom code in for a more robust accordion block, perhaps that has something to do with it? Screenshot is attached.

Our contact button in the header is fine, but every other button is a serif font (screenshot attached).

My site is culinarytourismalliance.com.

Help would be appreciated!

This looks like it worked!! Thank you so much!
