Remove PROVIDER column from Appointments+ page

At the top of the appointments page where it lists the user's appointments after they made an appointment, it shows the provider as "our staff" on my pc, and "a specialist" on my iPad. Is there a way to remove the column altogether since we do not allow selecting a service provider anyway?
I have removed the shortcode to select a provider but after the user makes an appointment, it shows PROVIDER at the top of the page. Please see screenshot.

Please help.
Thank you.
