My character has all the necessary qualifications for it, and I also unchecked the "proficiency" etc... boxes on the Add Item interface, but when I type in helm, that item doesn't show up. I searched it out on DNDBeyond in general and I found it, it shows for me, does not say that I don't own it electronically etc... How do I get this to show up in the Add Item interface?

When I look at the item (outside of the Add Item interface), it shows me the item information, it doesn't say "you need to purchase this". With other items that I've purchased, when I try to look at them and don't own them, they'll say that and give me a link to purchase. That's not happening here. I'd like to purchase just that item, not the whole module, if I don't already own it. But it's really hard to do that when it's acting like I do own it outside of Add Item.

Update: I had to find it by browsing on Marketplace, and I've added to my cart, but it used to be so much easier to look at the item and have that purchase link presented when one doesn't already own it. Not sure when that changed, but I liked the ease of finding the purchase link via Search. Another suggestions: add a Search feature to Marketplace.
