Er, I think you may have misread. Or perhaps I need to rephrase the ability.

As you are a member of a coven, you get access to the shared spellcasting feature when in this form, and have all the spell slots listed there.
You only get the shared spellcasting when in hag form, which is only for one minute once per long rest.
