I'm assuming you mean Koha 3.4, since there is no Koha 4 (yet). I think what you're describing is a known bug: http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=6362 A patch for this has already been pushed, so a fix will be in the next release. -- Owen -- Web Developer Athens County Public Libraries http://www.myacpl.org
