Font for page titles is not the one I have chosen in my font options

Hello, I'm using the Catch Wheels theme to build my website. I have a problem with the fonts. The automatic font for the titles (heading 1) is Rock Salt. My settings are : - font Tahoma for the content of my articles - font Josefin Sans for all the titles Unfortunately, when I click on my articles categories or articles themselves, the page title that appears is written is a weird stylish font that is never my Josefin Sans font nor the Rock Salt font. When I look at the Inspector to see the page code, it seems that the font is recognized at Rock Salt, but it's not. In the Customization menu, if I try to change the font and use another one, none of them work, as if the font choice for the headings never takes effect. Does someone has a solution? Thank you in advance for your help! Nicolas Note: I have the Catch Wheels Pro/Premium theme but I prefer posting my request here in the Free theme section so that anyone can access it.
