Include Post Thumbnail — NOT SHOWING — Help Please

If I create FEATURED IMAGE then I get the thumbnail (just like I want it just like I should), but it also creates a centered 2nd image…

So if no featured image is set, then there is no thumbnail.

If there is a featured image set, then I get TWO images… Which is crap.

Is there something I can enter into the CUSTOM FIELDS? Like “thumbnail” and the pictures URL?

How do I get this feature to work?! I want.. No, I NEED this feature to work!

Thanks,

Scott
