Very OLD Inventory Adjustment

In my continued clean up of the Dynamics GP 10 situation at my job here I am finding an Inventory Adjustment from 2012 that does not seem to have any transactions in it although on the Inventory Batch Entry window it has a transaction with 537 Quantity Total.  When I go into the Transaction window it is blank and when I open the Number -> Inventory Document Numbers it is also blank.  Any ideas if this is OK to delete or what might be going on?  I have run Inventory Reconcile at the year end.  Could that have impacted it?

Thanks!
