Bold writing is added

I ask the question again, because the first one is not answered. Or don’t want to answer, I don’t know.

CSS styles are changed on all pages of the site where this plugin is used. Or rather, the writing in bold is added headings, links, bread crumbs, etc.

Disable caching plugin – did not help.

To be honest, I’ve been waiting for an answer for 9 days and my problem is not being solved. In a fit of anger, I even wanted to rate this plugin 1 point, but did not.

Help me solve the problem!
