Cannot buy/sell items from merchants - Cyberpunk Red

[minjaekwon9]

Are you on the latest version of Item Piles?
Yes

Have you tried to reset Item Piles' system settings?
Yes

Describe the bug
An Assistant GM created a Merchant and no other users can buy or sell items from that merchant. They are able to open the merchant's sheet and the TradeMerchantItemDialog, but the Buy Item/Sell Item buttons don't do anything.

To Reproduce
Steps to reproduce the behavior:

1. Assistant GM creates a character and changes sheet to an item pile, then merchant.
2. Populate the merchant with items.
3. Other user attempts to trade with created merchant.

Expected behavior
When the Assistant GM trades with the merchant, the merchant works as expected and the button adds the item to his inventory and subtracts the correct amount of currency.

Screenshots

The Buy Item does not do anything unless you are the Assistant GM who created the merchant.

Is the GM logged in during the trade?

[minjaekwon9]

Yes, he runs the server from his computer so he's always logged in while I'm logged in. But for some reason only I can create merchants now. He can't convert characters into merchants anymore.
