Events+ capabilities not working

I am trying to get subscribers to be able to add an event on my clone site before I transfer it over to my live site.

I have activated user roles in Membership 2 plugin and made Subscriber a 'Basic Membership'
I have activated Event Capabilities and set '...Edit Events' under the role "Subscriber"

If I'm logged in as an admin, it works. If I log in as any other member it doesn't.

Please help
