Unknown System "To Set Your Password" Email – MJ

We are having the system generate temp passwords for our new users. Upon registration they get our welcome email, and a user name and the random password email all ok.

BUT

They also get a email with brackets in the subject line like this:
[Our Site Name} Your user name and password info

The body of the email says:
Username: their user name – To set your password visit the following address https://our path…

This is confusing….What is this and where is it coming from in MJ theme?

We can not find it and want to kill it.
