Featured Images Issue

I have the plugin installed, a few weeks ago.

Works fine so far, but it uses thumbnails not only as part of the post, which I like, but it also uses the same thumbnail as a “featured image,” which replaces the default image on the header of my blog with that thumbnail.

I would like to disable that function so that the header image can stay put. If it’s possible to still keep the option to post images as part of blog posts, I’m fine with that. Otherwise, I’m good with turning off thumbnails altogether.

Please advise; thank you!
