This has probably been mentioned before:
For the Feat that allows one to craft a Hardened Steel Greatsword the title in the Header does not match the item title. All other Hardened Steel weapon Feats the Perk title/header matches the item title/header that is unlocked. The Hardened Steel Greatsword is mismatched as Hardened 2 Handed Sword for the Feat title/header and Hardened Steel Greatsword for the craftable item title/header.
Not a huge deal but I thought I’d mention it anyway.
