Customized a responsibility from Receivables and unable to view invoice details in the Account Detai

My client is growing its customer base and so the Receivables department is hiring more employees to help them. As we do not want to give the new hires access to the full Accounts Receivables, hence we have customized a responsibility from Receivables. Now using this responsibility we are unable to view Invoice Details in the Account Details form.

This is what we do

Query for an Invoice by Transaction number. Click on Find. It finds it. Now click on Details to see the invoice, but nothing happens at this point.

If I click on Activities and then Details it will show me the payment details all fine.
