CPT how to change required fields for import .csv

Hello,

I got the CPT addon so I could make the address fields optional because my directory listings do not all have addresses. This said I could make those fields not required https://wpgeodirectory.com/docs/core-export/

I selected No for ‘Is it required?’ under the Custom Fields for addresses on my CPT, but my CSV is still not importing. The error says “434 item(s) could not be added due to blank/invalid address(city, region, country, latitude, longitude).”

Did I miss a step? How do I successfully import a CSV that includes entries that have addresses and some not?

Also, is there a way to make post_content optional for CSV imports? Or do you have a suggestion for what to fill for entries without descriptions?

Thanks!
