Adding extra zeros to event price

Hi!
I am configuring a calendar + events plugin (the normal versions), everything works ok except for a small but disturbing thing. Even though the ticket has the right price (for example 30 euros), the text right next to the quantity / add to cart text adds two extra zeros to the total.
When you go to the cart it shows 30, but it should not show 3000 as the total.

Here is a screenshot.
Has anyone had this problem=?
Thanks in advance!
