Similar to the issues reported in Bug 27934, the subscription table is not sorting correctly. In opac-detail.tt <td class="publisheddate"><span title="[% latestserial.publisheddate | html %]">[% latestserial.publisheddate | $KohaDates %]</span></td> <td class="planneddate"><span title="[% latestserial.planneddate | html %]">[% latestserial.planneddate | $KohaDates %]</span></td> If these lines are changed to use data-order instead as per: <td data-order="[% reserveloo.waitingdate | html %]">[% reserveloo.waitingdate | $KohaDates %]</td> <td data-order="[% reserveloo.reservedate | html %]">[% reserveloo.reservedate | $KohaDates %]</td> they sort correctly.
