Item was not foundNot An Issue

Hello. Does not buy or sell one product. What is the reason is not clear. Everything else will be sold and bought.

Here is the configuration in 2 views. Does not work.

"Bleach": {
"DisplayName": "Эфириум",
"CraftAsDisplayName": false,
"Shortname": "bleach",
"MakeBlueprint": false,
"EnableBuy": true,
"EnableSell": true,
"Image": null,
"SellPrice": 15000.0,
"BuyPrice": 150000.0,
"BuyCooldown": 0,
"SellCooldown": 0,
"BuyQuantity": [],
"SellQuantity": [],
"BuyLimit": 0,

or

The display name must match the item name you are making it.

"Bleach": {  <
"DisplayName": "Эфириум", <

So technically there is nothing wrong with GUIShop you are just creating the custom item wrong inside the config.

"Эфириум": {
"DisplayName": "Эфириум",
"CraftAsDisplayName": false,
"Shortname": "bleach",
"MakeBlueprint": false,
"EnableBuy": true,
"EnableSell": true,
