The setting section is specially for popup settings. It manages welcome and exit intent popup settings.

Under Welcome Popup section, select the form which you want to display when user lands on any page of your website. By default, cookie is set to 0 (zero), that means user will always see the welcome popup form whenever he/she visits your website. In order to avoid that, increase the number of days for cookie settings. ie; you can set it to 30. That will write the cookie to not display the welcome popup form for 30 days to that same user.

Similarly, select the Exit Intent form from the next section. Same settings for Cookie as well.
