CRM Portal - Remove contact preferences on profile

Hello,

I am trying to remove the "How may we contact you? Select all that apply" section on the profile page. I set site settings/profile/ Show Marketing options panel to false and

Snippets profile/marketingpref I have remove the value

I have cleared the cache and the section still remains, I also deactivated the snippet and site setting and the section still show on the form. I am using OOB customer self stater portal.

Cheers
