Hi Lee,
Having to confirm your identity to your Spanish bank is not unusual, especially for non-residents, as Spain's banking industry is responsible for the the EU's FATCA anti-fraud and money laundering regulations.
Do you have online banking with Caixa? If so, you can complete the KYC ("Know Your Customer") form online. In the Caixabank customer area, you'll find the form in your account Profile, in a section called "Work activity and operational profile".
However, I'm surprised Caixabank is asking you to complete Model 5433, given the consumer association, FACUA's, complaint to the Bank of Spain:

In your situation, I would complete the KYC, but push back on completing the Model 5433.
Good luck and kind regards,
Kim
