Thanks for your bug report. Did you /echo out all five items to see what $ibl() thinks is in the list?

ent sets mode: +bbbb ent!*@* *!*@entropy.* *!~ent@* *!*@*.undernet.org

* 5 & *!*@*.undernet.org
* *!*@*.undernet.org
* *!~ent@*
* *!*@entropy.*

It's weird cause there are only 4 bans.

If you type "//mode # +b" in the channel to list the bans, what do you see? This will return the bans that the server thinks are set on that channel.
