[c-nsp] Incompatibility for send-label between Cisco and Juniper?

Hi all
I encountered something strange with the neighbor <peer> send-label command under router bgp. When I attach a route-map controlling which labels to send, instead of restricting labels to send, it completely fails to advertise routes besides the one specified in the prefix-list. This problem does not happen between Cisco and Cisco.
Here are my output for the Cisco to Juniper.
With the send-label command:
test22#sh ip bgp neighbors 10.169.34.1 advertised-routes
BGP table version is 183, local router ID is 192.168.38.22
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
r>i192.168.38.19/32 192.168.38.19 0 100 0 i
Total number of prefixes 1
Without the send-label command:
test22#sh ip bgp neighbors 10.169.34.1 advertised-routes
BGP table version is 175, local router ID is 192.168.38.22
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
r>i99.99.99.1/32 192.168.38.19 0 100 0 i
*> 172.16.100.0/24 0.0.0.0 0 32768 i
*>i192.168.0.0 192.168.38.19 0 100 0 3 i
r>i192.168.38.19/32 192.168.38.19 0 100 0 i
Config as follows
address-family ipv4
neighbor 10.169.34.1 activate
neighbor 10.169.34.1 soft-reconfiguration inbound
neighbor 10.169.34.1 route-map TEST out
neighbor 10.169.34.1 send-label
route-map TEST permit 10
match ip address prefix-list TEST
set mpls-label
!
route-map TEST permit 20
ip prefix-list TEST seq 5 permit 192.168.38.19/32
Total number of prefixes 4
Hopefully someone can help me with this. Thanks.
