Help with a notification

Hello,

Please let me know hot to delete a dot from one of the notifications.

I have a mailto: link on one of my pages and when is activated, there is a message from CleanTalk Security saying something like “CleanTalk is checking the email” rather.

But, it has 2 dots at the end of the sentence. Not a big deal but it is for a writing competition and I do not want writers to tell me things ??

Thank you for your help! I would do it by myself, but there is no option on the dashboard.

Regards,

The page I need help with: [log in to see the link]
