After upgrading to Koha 24.11, existing lists do not appear in the Lists module. Lists created after the upgrade do appear. - The missing public lists all mysteriously reappear when you do an action in the filters row, e.g. click an arrow to order a column, or enter text in the List name then clear it. - The missing private lists mysteriously reappear when you: 1) do an action in the filters row, e.g. click an arrow to order a column, or enter text in the List name then clear it; 2) switch to the Public lists tab then back to the Private lists tab. - If you navigate away from the Lists module and come back to it, the lists have disappeared again.
