Trade cancels if using item as fee

Hey. I'm not sure what i'm doing wrong, but we're testing the plugin using scrap as a fee,  I have it set to use currency type 1 and made sure that both testers have tons of scrap in their inventory to cover the fee, but as soon as one of them accepts the trade it immediately says that it's canceled with no reason just "Trade cancelled"  If i go back into the config and change it to the no fee option, everything works perfectly fine between the same two testers. 

What could be wrong?

I may have hit send too soon on this. Think we figured it out. You have to click the accept button to get the fee container to open up. If you just type /atrade like the chat message says, that's when you do not get the fee container and it just cancels. Any chance that you could make it so that typing /atrade to accept the trade also pops up the fee container when a fee is set? Most of our players are used to pressing Tab - to open the inventory - to press our other UI buttons, but since the UI button on this is set as a Hud that fades into the background when inventory is open (and the inventory is covering the UI) it's impossible to click it that way.  If not, it's cool. I can adjust the incoming trade message to explain how to do it without going into inventory.

Sorry to keep spamming, But i'm also having issue where if the player clicks the decline invite button it says that there is no trade to decline. But if they use the /dtrade command it declines it. 

Hey glad my explanation made sense! Also glad you were able to push a fix so quickly. I would be glad to give this new version a test later tonight or tomorrow. Basically, I'm just glad as you can see.
