When editing transport-cost-matrix, it will save the numbers but not if you've enabled transfers. It also doesn't reflect disabled/enabled correctly from the database, so if you go in and make changes it re-disables them. To recreate: 1. Turn on the UseTransportCostMatrix system preference 2. Got to Administration/transport cost matrix 3. Edit a number of boxes to add numbers and uncheck the 'disabled' box 4. save 5. Observe that all (or most?) of the boxes are still disabled. 6. Run a report: select * from transport_cost where cost !='0.00' 7. Observe that they are disabled. 8. in koha-mysql: update transport_cost set disable_transfer = 0 where cost !=0.00; 9. Repeat step 6, they should have 0 instead of 1 for disable_transfer 10. Navigate to the transport cost matrix (don't refresh the page!) 11. Observe that the boxes are still disabled 12. Save (no changes needed) 13. Repeat step 6 14. Observe they are once again marked as disable_transfer 1
