Recurring invoice with Tax control amount

Hi,

I am trying to create a recurring invoice with tax control amount.

When I enter the required information (vendor info, calendar name, number of periods, invoice number, distribution set, first amount, tax control amount) and click on create recurring invoices, tax info section is blank with no data. If I continue and click OK, the invoices are created with same invoice amount and line amount. For example, if I enter Invoice amount as 100 and tax control amount as 10, line amount should be 90 but the invoice is created with line amount of 100. Please let me know if I am missing any setup.
