Products not indexed since early February

[ChromaMaven]

I see that my products have not been indexed in the marketplace since early February. The easiest example is to check the Business Cards category then look at my product feed (newest to oldest) to see the business cards that have not been indexed. Would someone please have a look at let me know when this will be fixed?  Thank you! @Scott

Apparently, the indexing is not happening in the back end of my store. I think it's okay in the public view of the store.
