Hello @xiano8494 and @boconpro,
Are you both using the “Unero Minimalist Theme”?
I just tested this with 3 themes and so far I can’t replicate the issue you are describing. I can see a single .woff file downloaded for the font-family and no extra files seem to be getting created in the uploads/2019/06
folder as I browse the site.
However, I don’t have access to the theme you’re using since it’s a premium theme. I can’t test what that theme does, and don’t have access to its code to see how they are implementing Kirki and what goes on behind the scenes.
The only thing I can suggest without knowing anything more about your sites would be to simply go to the customizer and make sure you have valid settings for your typography fields.
Have you tried contacting the theme author?
Premium theme authors could login to your site and debug the issues you have, something not allowed on www.remarpro.com tickets.
Your theme developer should be able to help you.
This seems more like an implementation issue to me or specific to your environment, but if it is indeed an issue with Kirki the theme-developer can share their debug findings with us so can fix it.
