Adding Membership to Events

I created an event using the Wix Events & Tickets app and there are sponsorship packages that I have added through the Pricing Plans app. When I create a plan and select the event under Benefits it gives me a red exclamation point when I try to save that says “First connect an event to a membership plan”. I went to the event and under Tickets and Seating the Membership Plans setting has all of them check marked (turned on). Am I missing something?
