RH Module

i've several trouble with RH Module :
i created an ADM project to support all kind of "absence" and i also have a strange project :
"PROJET PéRIODE D'ABSENCE"
but i'm unable to modify it ( impossible to add something ) & impossible to delete it
 

impossible to delete it and impossible to change something
 

i don't see it in all projets ????
 

According to previous point when i add "absence for someone" the worksflow "pour absence" doesn't seem to work 

i see nothing in "Tableau de Bord" RH
 

Thanks for your support.
