Notifications for job updates -- any way to modify?

Hi all, we work in Smart Projects, and one of the notifications that goes out to vendors seems a little sensitive. The notification that "job ### has been updated" is the one in question. This goes out to vendors assigned to a job when the deadlines or instructions are changed, which is great. However, it goes out even if we click in the instructions box at all, which leads to emails being sent when nothing is changed. We're wondering if anyone else has this issue, or if there's a way to change the settings or control what triggers the email. Any ideas? Thanks!
