[IRCServices] akill session limit bug when trying to remove

[PuterManCFC]

I seem to be unable to remove session limit akills through OperServ.

<OperServ> You now have Services super-user privileges.
<CF> akill view
<OperServ> Current AKILL list:
<OperServ> *@1Cust27.tnt1.two-rivers.wi.da.uu.net (by OperServ on Apr 22
2001; expires in 6 minutes)
<OperServ>     Exceeding session limit
<CF> akill del *@1Cust27.tnt1.two-rivers.wi.da.uu.net
<OperServ> *@1cust27.tnt1.two-rivers.wi.da.uu.net not found on AKILL list.

This is running on : ircservices-4.5.11 with Unreal IRCD 3.11

I am able to remove any other akills on the list, just not the ones placed
by OperServ.  Has anyone else had the same problem?

Thanks.
