Admin receives duplicate emails

Hi, the plugin is excellent, but it’s started sending many duplicate emails to one of the site Admins when they log-in (50 in one hour).

This is the body-text of the email

Hi
I apologize for the inconvenience. I have added your IP address to the allow list. Please let me know if I can be of further assistance.

I noticed the plugin’s log shows the Admin’s IP address differently to the other visitors. it is a longer string of characters, whereas the other have the usual 123.123.123.123 format.

Is the email from this plugin (if so, can I correct the spelling of ‘apologize’ for UK readers?.

Thanks
