Can't set economics

Hi i love your work!

And got already far, but the only thing i cant set right is Economics..

the vending machine treats the currency item as an normal item

(sells/ takes from me and players "paper" item)..

I do have the vending machine configured and saved with Bottomless flagg

Here are my config settings:

And

Please help :$ Last thing to finish a quest mission

^ Maybe that can help finding the problem ? ^ 

Npc TP does the same, the rest of my ten plugins (including Economics) dont have this error. Every plugin is up to date.
