currency & item not being removed or added

so far, i really love the simplicity of the UI and how amazing this pligin is, this is 100% what i was looking for, for so many weeks!

but, i came across some issues and id rather get support before i write my review.

1: when listed item, i use scrap, but the item listed does not get deducted / removed and the other player does not get money deposited. 
 

  "Settings Economy": {
    "Type (Plugin or Item)": "Item",
    "Plugin name": "Economics",
    "Balance add hook": "Deposit",
    "Balance remove hook": "Withdraw",
    "Balance show hook": "Balance",
    "ShortName": "scrap",
    "SkinID": 0

2: when i try to buy another of their same item, i get this error in return Below:

3: a lot of the pictures do not show up for some odd reason, some do and some dont, as pictured Below.
they show up fine when people find in loot, or lootboxes, or in their inventory.

4: Not an issue But, is it possible to maybe add feature to see the item ingame name? 90% of my ingame loot items are Named with custom names that people are very very used to seeing as well as since i have custom names for my guns for example: my L96 is called SIG SSG Sniper Rifle when people find it, or loot it, or drop it, or get it from console. is it possible that the listing can show the custom names instead of shortname?
