Hi,
To put-it in a nutshell, I have 4 profiles in this order: 
- Project Leader --> Order 310 --> defaults ProjeQtor rights (no modify on this profil)
- [Project Creator profile] --> Order 505 --> Reader rights everywhere but with creator rights on project. 
- [Visualisation profile]  --> Order 510 --> Reader rights everywhere (not reader+)
- [No rights profile] --> Order 520 --> Absolutely none rights everywhere

So, in my tree structure, I have this profiles for Albert : 
1 - Organization --> here [None rights profile]
   |1.1 - Direction 
     |- 1.1.1 - Service --> here [Visualisation profile]
         |- 1.1.1.1 - Pole --> here [Project Creator profile]

And when Albert create a new project --> he has Project Leader profile by default (it's his default profile on his account). 

With this configuration, I identify many bugs: 
 1 - Albert see currently all projects of Organization in Project selector and Today's page, even if he has no rights on all projects ! Actually, he should seen only  project of his service like it is on the planning view or project page. Can you fix this, please ? it's a source of confuse for users. 

2 - When Albert select project 1.1.1 (he has visualisation profil here) in selector project, when he create a project, ProjeQtOr select automaticaly this 1.1.1 on sub-project, (even he has no right to create at this level) --> if we change the sub-project before save, we can see in the liste, there is no 1.1.1 entry like it should be).Can you fix this, please ? Maybe this point is linked with the previous

ProjeQtOr V10.2.2 with PostgreSQL 14 on Debian Linux.
