Hi @KOUTNOUYAN ALAIN ,
All Items view is able to see only one item for the recurrence.This is by design. It spans those timings which are mentioned in recurrence and will display the cycle logo on the left side of the list. This view only shows non-recurring events to make all events more clear. If you still need to display all events, you can only switch views in the Manage Views instead of displaying recurring events in this view.
