Oracle EBS GST Tax lines

Hi There

When we create our tax lines (both AR and AP) via the India Tax Details form we notice that we don't get any visibility of these tax lines in the main invoice header, either in AR or AP. 

I notice in the Oracle document 'OFI-GST Order to Cash-phase-1' the screenshots for AR invoices shown an amount for Tax (see attachment and look in the balances Due section).  Is this something we should also be seeing after we have created the tax lines in the India tax details form, we don't see any value in the Tax balance in AR or the Summary section Tax field in AP?  We do see the correct GL lines created in the GL interface so from our limited knowledge it looks like it working in GL.  Maybe the Oracle screenshot is old as
