Performance routing with two Border routers and separate Master

I have a problem setting up Performance routing using two separate border routers.

I have a separate Master router (R3) with two Border routers (R4 - 59.0.0.4 and R9 - 59.0.0.9).
I am using static routing
R1, R2, R6, R8 are routers I use to generate traffic and their default route is R5
R5 has a default route to R9 (and a higer cost route to R4, altough I doubt it is required), (R5 is the default route for the internal network)

I am testing to 4 networks (10.6.6.6, 10.7.7.7, 10.8.8.8 and 10.9.9.9 hosted on router R7),

R4 and R9 have interfaces connected to R7, R9 and R4 are directly connected to each other.

R9 has a default route to R7 and a higher cost default route to R4.
R4 has a default route to R7 and a higher cost default route to R9.

I get a message on R3 as follows:
%PFR_MC-6-ROUTE_EVENT_INFO: Discovered exit BR 59.0.0.9, i/f Gi1/0 for traffic class Prefix 10.6.6.6/32
%PFR_MC-6-ROUTE_EVENT_INFO: Discovered exit BR 59.0.0.9, i/f Gi1/0 for traffic class Prefix 10.7.7.7/32
%PFR_MC-6-ROUTE_EVENT_INFO: Discovered exit BR 59.0.0.9, i/f Gi1/0 for traffic class Prefix 10.8.8.8/32
%PFR_MC-6-ROUTE_EVENT_INFO: Discovered exit BR 59.0.0.9, i/f Gi1/0 for traffic class Prefix 10.9.9.9/32
but do not see Discovered exits on R4, should I?

PFR tries to change the route when it goes Out of POlicy:
%PFR_MC-6-ROUTE_EVENT_INFO: Prefix 10.7.7.7/32: route changed to BR 59.0.0.4, i/f Gi1/0, due to load-balance criteria. Out of policy reason: utilization criteria

When I check on the two border routers I see the following routes:
Border router R4: (59.0.0.4)
sh pfr border routes static
Flags Network            Parent             Tag
XN    10.6.6.0/24
CE    10.7.7.7/32        0.0.0.0/0          5000
XN    10.8.8.8/32
XN    10.9.9.9/32


Border router R9: (59.0.0.9)
sh pfr border routes static
Flags Network            Parent             Tag
CE    10.6.6.0/24        0.0.0.0/0          5000
XN    10.7.7.7/32
CE    10.8.8.8/32        0.0.0.0/0          5000
CE    10.9.9.9/32        0.0.0.0/0          5000


After some time I get a notification that it cannot route out R4.
%OER_MC-5-NOTICE: Passive Unreachable OOP Prefix 10.7.7.7/32, No Egress  bw for 59.0.0.4, intf Gi1/0

Now I know the routing works as I shut down the interface on R9 connected to R7 and traffic routes though R4.

When PFR add the routes to the border routers should it not add a route to both R4 and R9, as if it only add a route to R4 then R9 is unaware of this route and continues to route directly to R7.
