Advice and answers from the Ahrefs Team

Ahrefs now takes the http protocol into account, so http and https will give different results in the Dashboard and Site Explorer. 

If there is no protocol specified (e.g. ahrefs.com) in the Dashboard, the returned result will be from both http and https

Thus, since domain.com, http://domain.com and https://domain.com are treated as different targets, these should be added separately in the Dashboard.
