What steps will reproduce the problem?
1.In survival mode, click on air while holding a villager spawner (default shop creation item) to select an alternate shop type like Book Selling, Item Exchanger or Buyer.
2.Select ANY shopkeeper (Creeper, Witch, Villager, Sign...)
3.Place a chest
4.Right click twice on it while holding the spawner.
5.Place Items of interest depending on the shop type
6.Configurate the shop (If posible. In case of Exchange shop type, no configuration shows on shift click, provably due to a bug)What is the expected output? What do you see instead?
The shop should be working according to it's type. Instead, no items show on the GUI allthough they have been properly configured.
The only shop that works is the basic Item Selling one.
With Book Selling, Item Exchanger and Buyer shop types, the result is that no Exchange items appear, Nothing does, just an empty GUIWhat version of the product are you using?
(Latest) v1.17.2Do you have an error log of what happened?
No error logs. Will turn debug mode ON if necesary.Please provide any additional information below.
I've only tried this on a protected world guard area... I don't think It has anything to do though. If any further testing is necesary to track down this bug please tell me.Also, please consider these command suggestions, I really think they would be really usefull and add the final touch to the plugin:

Seesm to work fine for me, though I agree that setting the different shops up is currently not very intuitive / could need better documentation:
BuyingShop: buys items you put in the chest for economy item (gold, emeralds, ..)
To set this up: put one item of each type you want to buy into the chest AND add enough economy items. Then go into edit mode and click the slime ball / economy item there to in/decrease the costs. The shopkeeper will only display those trades for which there are emeralds/gold (or whatever you have set up) in the chest.
TradeingShop: You put in the item you want to trade away into the chest and then open the shop in edit mode, and click an item in your inventory and then a slot in the edit window to insert the item there as cost.
BookShop: You add the signed book into the chest and as many book-and-quill-items as you want sell books. The go into edit mode and click the slime ball/economy item to increase and decrease the costs for the book. The trade will only be visiable if you have added enough empty book-and-quill-items to the chest as well.
