Compendium won't show items from the Dungeon Master's Guide...

My compendium is doing some wacky stuff

I can't access any data at all - It only shows the SRD which is usually what it does when you don't have any books.

But I do have them, they're turned on in the game settings - Really unusual issue:

Hi DM Steve, 

Please turn off the new compendium and see if the problem continues. 
You can do this by going into your game, click the My Settings tab (top right corner) then turn off the New Compendium.
