Variation Family mixed up with Virtual Bundles

I have a variation family that was selling very well. Suddenly the best-seller ASIN showed up out of the family, as a standalone ASIN. I've tried updating the SKU via a flat file upload and the ASIN shows up in the variation family in Seller Central, but it doesn't on Amazon.com

Here comes the strange part. Amazon associates started talking about virtual bundles on the cases I've opened regarding this issue. I thought these were the usual automated responses going wild, but after hours I realized that the parent ASIN of the family was a virtual bundle (associated with some of the ASINs of the same family).

When I enter the variation family page for this family, I see the correct SKU I've created but the title of the family is one from a bundle, and the URL where it leads you contains the SKU of the bundle as well.

I've now deleted all the virtual bundles associated with ASINs of the family but the ASIN is still not showing up inside the family listing in Amazon.com.

Anybody has experienced any issues like this?
