Why is the route imported from global into vrf NOT advertised ?

I have a router with vrf import and export between vrf s and vrf and global as follows:

R1
ip vrf CustA
rd 100:1
import ipv4 unicast map UNICAST
route-target export 1:1
route-target import 1:1
route-target import 2:2
!
ip vrf CustB
rd 200:2
import ipv4 unicast map UNICAST
route-target export 2:2
route-target import 2:2
route-target import 1:1
....
ip prefix-list DEFAULT seq 5 permit 0.0.0.0/0
!
route-map UNICAST permit 10
match ip address prefix-list DEFAULT

On R1
mixing#show ip bgp vpnv4 all

Why is 0.0.0.0/0 NOT advertised to 3.3.3.1 ?
