The Sell Items view doesn’t have an End Date. It just shows you which Items still have Quantity available to list on any site.
If you want to find recently ended listings, use the Check Listings mode and search for those that have recently ended. To list them again, select them, right click and “Goto Items for these Listings” and submit them again.
If you’re using one of the Enterprise editions, you can assign Allocation Plans to do this automatically when Listings end with unsold items.
