Purchase Receipt Defaulting wrong warehouse location on detail lines

Having a tough time getting the Purchase Receipts to default the Warehouse and Location.  It is defaulting the warehouse but the location just shows <Split> and won’t fill in the default from the Item Warehouse Record.

Here’s the scenarios:

When doing a Purchase Receipt you have multiple options to enter the Detail Lines on the Receipt.

1. <Enter Receipt> from the PO Screen – this builds the Receipt entry from the PO and does all the settings.  Detail Lines to not have a Default Location.  They do have a Default Warehouse
    
2. Manual Entry – this seems to work properly when you enter the Detail line with Inventory ID, the Warehouse and then the Location Defaults from the Item Warehouse default Receiving Location
    
3. On a Manually Created PO Receipt – select the <Add PO> button which will show a list of POs from this Vendor which you can select and will fill the Detail Lines – no Default Location.  They do have a Default Warehouse
    
4. On a Manually Created PO Receipt – select the <Add PO Line> button which will show a list of the open PO Detail Lines for this vendor

This seems to be a bug.  Why on #1, #3, #4 does it not pick up the Item Warehouse Default Location.  It just shows <Split>.

Any help would be appreciated.

Thank you
