Default Registration Number can't be updated in Supplier

Dear Experts,

We are currently working with OR12.2.8 We recently updated a supplier taxpayer id and default registration number, however when we attempt to save the record an error message prompts "This tax registration number is already in use for party type: Third Party and party name: INMOBILIARIA HOTELERA EL PRESIDENTE SAN JOSE DEL CABO S A P I DE CV for the same period." We checked our suppliers and we do not have any supplier with that registration number and with that name.

We go back to look for the supplier that has that Default Registration Number and we can't find a supplier with that name.
