To test:
1 - Browse to 'Administration->Circulation and fines rules'
2 - Make sure you are editing 'Standard rules for all libraries'
3 - Set 'Lost item fee refund on return policy' to 'Refund lost item charge and charge new overdue fine'
4 - Swtich to edit rules for a specific library, click on the dropdown for 'Lost item fee refund on return policy' and note default says 'Use default (Refund lost item charge and restore overdue fine)'
5 - Switch default/all libraries rule to 'Refund lost item charge and restore overdue fine'
6 - On specific branch note the default option is now 'Use default (Refund lost item charge and charge new overdue fine)'
7 - Apply patch and repeat, note the default descriptions now display correctly
