[c-nsp] Deny default route (From customer - BGP)

Hi Everyone,

Only had a few hours sleep, so I may be overlooking something extremely obvious...but we are receiving a default from a customer, even though route-map/prefix list *should* block it...
router bgp xxx
...
address-family ipv4
...
neighbor CUST_A route-map CUST_A-BGP-IN in

ip prefix-list PL_DENY_DEFAULT seq 5 permit 0.0.0.0/0
ip prefix-list PL_CUST_A_BGP_PREFIXES seq 5 permit xxx.xxx.xxx.0/24

route-map CUST_A-BGP-IN deny 5
match ip address prefix-list PL_DENY_DEFAULT
route-map CUST_A-BGP-IN permit 10
 match ip address prefix-list PL_CUST_A_BGP_PREFIXES
 set community xxxxx:1400

Weird thing is, that "sh ip bgp summary" shows that neighbour as only having 1 in "State/PfxRcd"

but "sh ip bgp nei xxx.xxx.xx.xx received-routes" shows the neighbour with 0.0.0.0 and there single /24

Cheers for any help.
