Invoice approval screen shows 0 amount to pay for consolidated invoice

Hi,

We have below scenario (OTM version: 6.3.7)

Shipment A having cost 100 USD
Shipment B having cost 100 USD

Create standard invoices for each shipment, consolidate to make a parent, approve the parent invoice. This works perfectly.

Now user puts extra 50, 50 USD cost on each shipment A, B. Created separate invoices with invoice adjust cost action, now create a consolidated invoice from these two new invoices and try to approve the consolidated invoice.

Here the screen shows amount to pay as 0 USD, however it should show 50 USD. Any idea why OTM is behaving as such?

Appreciate your help!

Thanks,
Prateek
