When a user checks the box to opt out of receiving course emails on their dashboard, the box does not stay unchecked when the user saves their changes. To the user, it is unclear whether they have successfully opted out of emails.
Steps to reproduce:
1. From https://courses.edx.org/dashboard , select the gear next to the Twitter/Facebook/View course buttons.
2. Click "Email Settings."
3. Uncheck the "receive course emails" box and save your changes.
4. When the dashboard refreshes, look at the same course's email settings again.
Expected: "Receive course emails" box remains unchecked.
Observed: "Receive course emails" box is checked.
This was reported by MITxPRO. I was able to reproduce on edX.org and white label sites in Firefox and Chrome.
