Collection question... Not understanding.. "need to resolve to make the collection visible?"

Zazzle Collection question...  This is the only collection that says this and I don't understand it. After clicking on Zazzle Marketplace it shows two things that they say I need to resolve to make the collection visible. Then it says "All required products must be added." and it also says " Minimum of 5 recommended products, excluding styles." I'm not sure what they want me to do here. I thought this collection already had a cover image, so ... ? Also, if I click on the "Zazzle E-mail", it also says "All required products must be added." and it also says " Minimum of 4 recommended products, excluding styles." And it talks about "Post Purchase Collection", under it it says "Zazzle will send customers who purchase a product from this collection a follow-up email showcasing the rest of your collection. Customize the text to create a personalized message for your customers, resulting in a stronger connection with your store and the potential for increased sales and traffic. Highlight the event or occasion and emphasize the unique features that set it apart from other collections, making it irresistible to customers." Then it has a space for me to enter text. I have never seen this before. Why is it only this collection that says all of this..?

I would guess this is the only collection of yours that is of the Cross-Sell / Event Suite type, as that is the only collection type that has the Zazzle E-mail option and the only type I am aware of with required and recommended products. If you are on the collection editing screen, there will be a section titled "Recommended products" with a lot of boxes labeled with product types. If you have any products in the collection for a given product type, a picture of one will show up in the relevant box. You need to fill at least five of the boxes to make the collection visible - and at least one of those boxes must be the required product, which should be the first box shown.
