"Events Booking - Event Categories" problem

Hi, I've a problem.
I've installed Kilix template (I had a previous one older and I decided to change) and I've uptated EB BUT NOW the component "Events Booking - Event Categories" doesn't open correctly the first one in the list.
After the selection of the first option in the component, it opens for the first category "Kryon con Lee Carroll" category an empty space so It's impossible to subscribe but works properly in other two categories.
Can you help me? I need the registration return online as soon as possible for this event!
Here some images
Thanks for help!

another info: the component Events Booking - View works well and I see also the missing event. So it seems a problem of the Event Categories component.

I used for now a solution (I created a component that works similary) so it's not so urgent.
My work will have no damage.
But will be important to understand the problem

I like this software and also you template is great

The team support helped me very fast
a simple solution: recreate another category and re-assign the event to the new one. so the problem with alias menu solved in a very elegant way.

all works now
