Mailchimp newsletter subscription form in the customer dashboard menu

Hello,

I’m soliciting you today because a registration form for a monthly newsletter from mailchimp “recognized thanks to the short code” is displayed on the menu of the client dashboard without having set one.

It should be noted that I do not have the MailChimp plugin installed and that even by changing my current theme, the registration form does not display.

Could you help me to solve this problem?

Have a nice day,

Thami
