Resource not being assigned correctly

Hello here,

I have a resource (me) assigned to a project.
This project contains activities on which this resource is assigned on.
The planning calculator does not calculate the duration correctly ; the activity is displayed inside planning per resource but with no duration for these activities.
When I look at the project planning, it does display the activity but for the day of today and with a duration of 1 day.
Screens below :
Affections of the resource "not working" :

Best regards,

Jordan
