Eliminate old Probes

Hi, some time ago I connected my Turris Omnia, via software, to the Ripe Atlas project. Now I’ve done it again, but the two old connections made with an account that no longer exists still appear to be open. So I keep getting emails warning me that the Probes are not connected. Is there any way for administrators to delete them? So that I no longer receive related emails? If yes I can give in tried the email address associated with those old Probes. Thank you.
