Hey Snip3rDragon,
I currently am having this problem on the Xbox One. I have searched the net and found a variety of different options to reset merchant loot (non of which work for me sadly).
- Save in an area that is NOT the Hissing Waste. Visit the Hissing Waste merchant. Load Save in other area and repeat.
- Save in an area that is NOT the Hissing Waste. Exit to Main Menu/Close Application entirely. Load and visit merchant.
- Some report success when changing your internal clock forward. Visit merchant to see if changes occur.
A note may be to make sure you have "The Short List" perk before unlocking the Hissing Waste area. This may be a tedious step, but could prove fruitful (I tried this and saw improvement in the Keep Merchant but not Hissing Waste).
I was glad to see I was not the only one encountering this problem. These methods have worked for other players and I would recommend giving them a shot and see if this resolves your "The Short List" perk issue.
