I have a published hub about a couple of months ago, showing on my profile page, but it is not showing on the drop-down list to highlight. Is there a reason for that, or are all published hubs not on the drop-down listing to be able to highlight?
I had this problem and what it was for me was the picture. I had one but not strong enough I think, maybe not enough pixels, not real sure but anyway just getting a good picture made it show up, right away. Hope this helps!
