Problema asignacion de recursos

John-project 

First of all thank you for your help

The project calendar is 

The task calendar is 24 hours

Task type
         Fixed units and conditioned by effort

Scheduling doesnt ignore the resource calendar
The task duration initially, before asign resources is 24 hours, and the work duration 24 hour as well. If I asign the first resource, with morning calendar (6:00 am to 14)  these times stay the same. When I asign the second resource, with the same calendar, the duration reduce to 16 hour and the work remains at the same value 24 hours. When I asign the third resouce,  with afternoon calendar (14 to 22) the duration increases to 16 hours and the work remains al the same value 24 hours. And with the fourth resource with afternoon calendar, the duration reduces to 14.4 hours and the work remain at 24 hours. But there are hours free of work in afternoon resource and asign hours in the morning resource the day after. I dont understand this situation
Task without resources

Task with one morning resource

Task with two morning resources

Task with two morning resouces and one afternoon resources

Task with two morning resorces and two afternoon resources

And this is the problem with the scheduling

The afternoon resource has free hours, and the morning resource work the day after

The project stardate is 25/03/2024 9:00 and the end date is calculated

Where is the problem?

Thanks for all
