Why ain't my invoices registering under the supplier?

For some reason recent invoices are not being tagged under the Suppliers detail.
When I look at a supplier and ‘click’ view invoices, some aint registering in, even though they register under the ‘payments made’ section.

Whats going on?
please help as everything is not clear as it was. This is happening to a number of suppliers on my records.

Have you looked under archived?

I can see one supplier with about 10 archived invoices. If you want to un-archive them just select the invoices go to the more options menu and select restore selected.
