Can't define type for store in v6.7

RouterOS General
1

I am trying to create a store for a Web Proxy in ROS v6.7.
If I use the command
/store add name=web-proxy disk=sata2
it prompts for type: as expected.
If I hit ? there are no choices listed.
I have entered
add name=web-proxy type=web-proxy disk=sata2
and it returns the error
input does not match any value of type
What am I missing in creating a store?

You must enable the proxy first.
