Red and Blue LED's won't turn off, Selador Vivid 11" Classics.

I recently purchased 10 Selador Vivid 11" Classics from  Nine of them are working great, but on one the red and blue LED's won't turn off completely.  I seem to be able to raise the intensity on them but when I fade them down they get to a medium point and then won't go down any further. 

I wanted to check here to see if anyone has already dealt with this before I go and take it apart.
