I have exported invoice data from odoo7 and imported into odoo9.

When I go for register payment for those imported data of Open invoices, payment for those invoices can be done successfully but invoices state still remain same(i.e.Open) instead of Paid state.

I have already checked all configuration like checked on Allow Reconciliation in account, set income account etc. All configuration are proper as per requirement.

Can any one help me regarding it?
