Hello Marco,

Could you check if "ALL" or "none" categories are selected in the "Filter by Category" Option ?

If you have only "red" and "green" categories selected, it is normal that you don't see them.
If this option is empty, all categories will be displayed by default (as no filter set).
And if with this option empty, you don't see all events, check the menu options to the list of events

Hope this helps ?

Best Regards,
Cyril
