How is Agenda/Events supposed to be used?

For a particular third party, I went to Events/Agenda and added an upcoming event (visit their office) on wednesday (see first image). In Dolibarr main, this event is not shown up in the Agenda widget and if I manually go to the global Agenda I cannot find the event I just added (second and third image). I can find it if I go to the third party and Events/Agenda, but I think that defeats the purpose of having a global Agenda.

Somehow the forum doesnt allow me to upload images, so they can be found here:
