Font still loading from Google

Hi there,
I have an issue with your plugin, unfortunately. Your plugin only found 1 font (Quicksand) but there still is a Dosis font loading from fonts.gstatic.com (7 times).
I cannot find where this is coming from and why it’s loading it from Google as there is also nothing inlcuded in any CSS file. How can I replace that with a local font as well?
I set up an empty test page where it is still loading. (added link to post)
I already received a written warning from a lawyer taking advantage of this issue by sending out letters to thousands of website users in Germany at once. That’s why I need to fix this somehow.

Thanks!
