PFR Uncontrol Appl Prefix, Exclude prefix failed so uncontrol traffic

Hello Everybody,

 

I´have set a Lab with

 

2 Routers, one is the MC/BR and the second is the second Border.

Here is the configuration ont MC/BR

 

MC_BR#sh pfr master

OER state: ENABLED and ACTIVE

  Conn Status: SUCCESS, PORT: 3949

  Version: 3.0

  Number of Border routers: 2

  Max prefixes: total 5000 learn 2500

  Prefix count: total 46, learn 30, cfg 0

  PBR Requirements met

AS you can see on the configuration , i have used an automtatical Learn for Application, as the Border are connecting to the ISP or Internet , i don´t have BGP, i just use a static defautlt route with a parent route pointed to the ISP.

So i can´t configure a specific prefix for the ISP because i don´t know all the prefix people surf on the internet ?  so i let automatic learn

 

It appear that the PFR can´t optmized the application  traffic learning automatically with this error :

 

*Oct 30 11:53:43.957: %OER_MC-5-NOTICE: Uncontrol Appl Prefix 93.184.219.0/24 http, Exclude prefix failed so uncontrol traffic

MC_BR(config)#pfr mas

MC_BR(config)#pfr master

*Oct 30 11:53:44.169: %OER_MC-5-NOTICE: Uncontrol Appl Prefix 173.194.41.0/24 httpssl, Exclude prefix failed so uncontrol traffic

*Oct 30 11:53:44.661: %OER_MC-5-NOTICE: Uncontrol Appl Prefix 80.94.76.0/24 http, Exclude prefix failed so uncontrol traffic

 

So i don´t know how can i solve this problem ? and what is the meaning of this log

 

Here is the Policy that i have :

WHEN i debug on Border i get this message :
