Invalid Supplier id: 0 error

I have a problem with one product in the back office.

When I try to edit it via the catalog > products menu I get the error:

I checked the table 'ps_supplier' and as expected there were no suppliers set up.

I checked the table 'ps_product_supplier' which included records.

I deleted all the records in 'ps_product_supplier' and all works ok.
