We have fixed a long outstanding bug where the Insurance Detail drop-down selector under the Jobs > Shipments screen would occasionally behave erratically. This would typically manifest itself as the selector reverting to the previously selected or default "Not Set" values.

Note on Drop-down Selectors: If the last value you set for a record is set via a drop-down selector, it is always a good idea to hit the TAB key on your keyboard to force the change to be committed to the database.
