An FBA item no longer has the badge or “Buy Box”. I’m the only seller.

I’m the only seller for a certain product. It sells okay, but I’ve noticed it hasn’t sold in a while. I found the listing and it’s turned into one of those listings that doesn’t display the Prime badge or display a buy box. It has the “See All Buying Options” button, THEN it shows the Prime badge.

Also, when you search for the item, there is no Prime badge anymore. Is there a reason for this? I’m the only seller so it’s not like there’s competition.
