Cannot create Redis cache in Enterprise subscription

I'm trying to create a Redis cache in an Enterprise subscription but portal.azure.com only allows me to select my MSDN subscription. In the dropdown at the top of the portal that opens when I click my name I can see Directories. That lists Default Directory (with my my msdn subscription below), Standard catalogue (my enterprise subscription) and xxx (a resource group).

When I select my enterprise subscription it always reverts to my default directory.

When I try to create a Redis cache, in the Subscription selection, I can only chose my Msdn subscription.

Is this supposed to work?
