Preload key requests

I have been using Social Warfare for a while.
I recently updated it to the latest version, when I check my page speed with Google . I get this error

Warnings: A preload <link> was found for “https://pagead2.googlesyndication.com/pagead/js/r20190610/r20190131/show_ads_impl.js&#8221; but was not used by the browser. Check that you are using the crossorigin attribute properly.

The url google points me to is https://howto9ja.com/wp-content/plugins/social-warfare/assets/fonts/sw-icon-font.woff?ver=3.6.1

I went to the plugin folder in my cPanel and deleted it, yet the problem persists.

If I deactivate Social Warfare, does all my social share counts go also???

BUT I’ll be really happy if you resolve this issue.

Thanks from HowTo9ja

And for the record, I came across a forum about the same error and was resolved after they deactivated Social Warfare, PLEASE!!! I don’t want to deactivate Social Warfare. Thanks
