I noticed that after upgrading to version 2.9.0 Build 702, the supplier reference numbers in the column have disappeared on all the items that are combinations. Then today I imported a group of items that are not combinations, and the supplier reference numbers do not show up after the import. I can manually enter the number, but it should show after an import. It takes a long time to manually enter the number for each item. I will check later with my partner who has not upgraded her software to this version to see if they show on the earlier version or not. I also notice now on the right lower corner of the main tab of the edit item window, the options for whether to allow orders if the item is not in stock are not there any more. Is this a bug?
