ip split horizon letting ospf routes slip through

hello group,

i have routers R1, R3 (FR spokes) connected to Hub R5. R1 is advertising route 155.2.146.0 to R5, but I do not want R5 to send this update to R3. So, I have configured "ip split-horion" under R5's physical interface (subinterfaces not used). But it seems R3 is still learning the route from R1:

O 155.2.146.0 [110/65] via 155.2.13.1, 00:10:27, Serial1/0
                    [110/65] via 155.2.0.1, 00:10:27, Serial1/1

Config of R5

interface Serial1/0
 ip address 155.2.0.5 255.255.255.0
 encapsulation frame-relay
 ip split-horizon
 ip ospf priority 2
 frame-relay map ip 155.2.0.1 501
 frame-relay map ip 155.2.0.3 503
 frame-relay map ip 155.2.0.4 504
end

Config of R3

interface Serial1/1
 ip address 155.2.0.3 255.255.255.0
 encapsulation frame-relay
 ip ospf priority 0
 serial restart-delay 0
 no dce-terminal-timing-enable
 frame-relay map ip 155.2.0.5 305
end

Config of R1

interface Serial1/0
 ip address 155.2.0.1 255.255.255.0
 encapsulation frame-relay
 ip ospf priority 0
 serial restart-delay 0
 no dce-terminal-timing-enable
 frame-relay map ip 155.2.0.5 105
end

Any idea what i am doing wrong here?

Thanks in adv
-Ahsan
