Can't use create function for Young Dragon (Help pls)

I'm trying to use the Young Dragon gloves in the create option at my clan base, but it won't let me drag them across, it also doesn't let me pick up anything else in my bag. The NPC is "Wu-Tang Truist (Xuanxuan)". I have both materials for the trade, not sure if I'm not using it right or its glitched.
Any help would be great, thanks

 

Try right clicking the items instead of dragging them. Also try reloging.
GL!

 

Ahhh finally, thanks, the right clicking worked. Thought i'd tired that, but obviously not....
