Is anyone else having trouble upgrading attack and attributes?

[JRomes04]

On Star Wars, Galaxy of heroes... upgrading the character's attack and abilities is not working for me even though I have enough of the cantina items required. 
Just to give an example of what I am talking about:
My character level is 64
Count Doku is level 64 his force lightning is level 5 and to get it to level 6 requires 8 green items and 7 blue items from cantina. I have 190 green items and 41 blue things yet I cannot upgrade even tho i have the 15,100 to do so.

This goes for a number of other characters. 

Any help, advice or solutions?
