Fonts are all different on checkout page

-- HikaShop version -- : 3.5.0
-- Joomla version -- : 3.8.10
-- PHP version -- : 7.0.25
-- Browser(s) name and version -- : safari 10.1.2

On this page, like 6-8 different fonts are being rendered. My template is by rockettheme and it's new but this is the only page where I'm seeing so many different fonts. Suggestions on how to hand that? I'd like one smooth presentable page.

Thank you in advance.

The dev pages are dev5.seleatherfest.com/home but in order to see it, you'd need to login, put something in the cart and then you could see the check out page which is why I sent a screen shot. I didn't see the link to hide credentials to provide login info so you could duplicate.
