Exclamation point in yellow circle on New Move In Report

My wife was just called as a ward RS President. While reviewing the New Move In Report, she sees an exclamation point in a yellow circle by most if not all families. What does that mean?

... I'm going to guess that it indicates that no ministering assignments have been made...

Thanks!

If it is an exclamation point inside a yellow triangle, it means they were moved into your ward from "address unknown" so they may have not had contact from anyone in the church for a long time. I don't think I have ever seen a yellow circle on that list. On my report, there is a light blue panel at the top the explains the symbol.
