Sometimes you are not happy if you get more than you want....

We (ACOnet, the Austrian NREN) currently think of what tool we should use for building our IPv6 BGP filters. Currently we use RtConfig version v4.8.5 and I tried to use version 5.0.0 now.
One problem that makes me nervous is:
If I enter:
echo "@RtConfig import AS1120 188.8.131.52 AS16099 184.108.40.206" | ./rtconfig -disable_access_list_cache -cisco_skip_route_maps -cisco_use_prefix_lists
I'd expect _one_ prefix-list beeing generated - currently only for IPv4. But I get two:
no ip prefix-list pl100
ip prefix-list pl100 permit 220.127.116.11/24
ip prefix-list pl100 deny 0.0.0.0/0 le 32
no ip prefix-list pl101
ip prefix-list pl101 permit 18.104.22.168/26
ip prefix-list pl101 permit 22.214.171.124/26
ip prefix-list pl101 permit 126.96.36.199/17
ip prefix-list pl101 permit 188.8.131.52/20
ip prefix-list pl101 permit 184.108.40.206/20
ip prefix-list pl101 deny 0.0.0.0/0 le 32
Two questions now:
1. is it a rtconfig-bug or is something wrong with the autnum-object of AS1120?
2. is there a newer release available than 5.0.0?
thanks in advance for any hints,
