Header font changes automatically on certain pages?

[UK_Aspire_Vendo]

Hi folks! I hope everyone is well.

I'm designing a site for a client and for some reason the heading font on our site changes to something other than what I've selected in the theme editor (I went with Zurich) quickly after the page starts loading.

The thing that makes this strange is that any page where a product can be visible this is happening. Any page that is a designated shopify "page" the font stays put. 

Can anyone shed any light on this for me please?

The site is https://bardeliquid.com and the password is bardayit

Thanks in advance!

I have fixed this myself by editing the base.css file and adding in the following:

.header {
font-family: Zurich Extended !important
}
