how do i remove a contact from a group

i have a section of the web page called "my group contacts" and under there there are several groups.

I have used the "add to" button while in contacts to add various email addresses to these groups. This is different from "invite to group" because these people dont need to be zoho users.

But, now how do i remove one of those email addresses from the group contacts?

(if there is a way, can i change this post from a problem to a question)
