When you hover over ghost shells in the collections tab and hit the "e" key (on PC) it shows you how to get the item. I've noticed that this season and last season's ghost shells say source: eververse in the collections tab. These are season pass items. Season pass items are supposed to say source: season pass reward. There might be other items that are also doing this but these are the two that I personally noticed. This should be corrected. These are not eververse items, they are season pass items.
