Different fonts show on mobile version of site

Hello guys,

In my desktop version of my website I use a certain font, Valken, for some of the text. (I have other fonts in my project beginning with valken, but the specific font I’m talking about is just called “valken” with nothing after it) The font shows up perfectly on the desktop but switches to a different font when I look at the site on a mobile device. I really don’t know whats going on and my teacher at school couldn’t help me. The only thing I think it could be is this: when the text is selected, in the typography category a font is not necessarily selected, it just says “Select…”. Every time I try to choose a font it just goes back to “Select…” but still shows the font on the site. Please help if possible.

Thanks.
