IOS-XR OSPF NSSA RFC3101

Hello, i'm doing some lab with IOS-XR and i have one situation strang, basicaly i have a NSSA area with multiple exit points and a redistribution ocurs inside the NSSA area.

 

The problem basicaly is: PE10 receive the NSSA route with P-bit set and send it to PE6 via area0, PE6 receive it (Type5) end flood it inside NSSA again... but PE6 already has a NSSA route for this prefix... but it delete it from database and install Type5 

 

RFC3101 route preference says:

1. A Type-7 LSA with the P-bit set.
2. A Type-5 LSA.
3. The LSA with the higher router ID.
The P-bit default is now defined as cleared.
 
i my understand IOS-XR dont uses RFC3101, i search in documentation and not found about it and i dont have any solution, anybody seen this behavior?
 
If i cancel P-BIT NSSA is installed successfully, really the problem is OSPF path selection order
 
Same situation in IOS-XE works according the RFC3101
