Restrict Woocommerce customers from Members Only pages/content

I’m using Woocommerce so people can register for an event. And I’m using WP-Members so only members can access certain areas of the website. When someone (not a member) registers for an event (via Woocommerce set up) and they check the box “create an account,” they are then able to access the content I have restricted for ‘members.’

Does anyone know of a way to make it so those people that want to create an account when they register for an event can’t access the restricted pages? (They create the account so their info is stored so they don’t have to keep re-entering their information when they register for future events.)

Site is sda-seattle.org.

Thanks.
