I too only have Moon+ as a reader app and when I select an epub in CC it opens up straight to Moon+.
When you open a epub from a file browser it opens in Moon+ fine?
Is the difficulty opening from CC only when you are connected to the content server, wirelessly connected, when not connected, or all three?
On the surface it seems to be unique to your tablet, maybe chaley can lend some insight.
