Deactivated Purchasing Category using "Inactive On Date" but now need to re-enable

I end dated a purchasing category so it can no longer be used in iProcurement.  To Deactivate I added an end date in the Inactive On field.

Unfortunately, now I need to re-able the item category however I am prompted with the following message when following the below steps.

"This combination has expired."

1. Setup> Flexfields> Key> Values

Value Set Name:

HUM_ITEM_SUBCATEGORY_CODE

Independent Value: [Insert Segment1]

2.  Setup> Items> Categories> Category Codes

Structure Name: Item Categories

3. Setup> Items> Categories> Category Sets

Name: Inventory

Please advise if I have the ability to re-enable the categories after it has been end dated.
