Second event is not displaying the Marketpress product, which is holding the variations.

Hello.
I am using Events+ together with MarketPress to have multiple priced entry options.
I follow this movie: https://www.youtube.com/watch?v=W-y_h1RR4pg&feature=youtu.be

I have added a single event to Events+ and added the MarketPress product without any issues.

But, now when adding a second event, the same kind of event, just another date, it is not displaying the marketpress product, which is holding the variations.
Could it be that Events can only use a product once?
Is this intended behavior? As I would have to create a product for every date the event is on.
