Required field on form, but not populating data into my Monday.com board

Hello community: we have been using Monday.com for a few years now. Just in the last two weeks, my “required” telephone number field on forms is not populating my board.

I have been told by support that if a customer/client presses the space bar, they can bypass entering in their phone number on our forms and then submit the form, even though this field is “required.”

What is the fix for this?

And that column ‘type’ is phone?

Yes, it is a “phone number” column.
