When you acess tailoring table you get into first menu. There are Cloth, Leather armor, hide armor, Products, and healing kits in this order. Up to hide armor all works fine, you can choose any item in the subselection and you see correct required material and correct description of the item. But when you choose Product and choose any item in that subsection, it shows required material and name of some Studded leather armor in description. Then if you choose Healing kits section and choose one of the healing kits avaivible to craft, you will see description and required items of one of two products (those that are first listed in product section). Thus i think there is section with Studded leather armor missing.
Added pictures for better understanding
This is main selection
As you can see there are 5 main crafting groups
If you select Hide armors and choose Hide armor all works fine .. pay attention to both item name on selection and on item name in description field as well as materials
Then we go back nad choose Products section and we select first item there, Leather bag. See that item name in description differs from name of item and also material logically wont make such item
Then we go again back and choose healing section and first healing kit there. As you can see it shows item name and material for Leather Bag, that was first listed name in previous section.
So i made assumption that there is missing studded leather armor section in main menu between Hide Armor and Products
