Strange. I have not come across this. So, I suggest you report this to Apple.

Provide Apple Feedback:

Do your Part: Report this update issue to Apple.  Apple Support will not get back to you directly, but the more feedback they receive on this, the more they will know what is going on and what needs to be fixed.

1. Go Here: Feedback - iPhone - Apple
2. Select: "Bug Report" for the "Feedback Type"
3. Comment On: When you came across this, and how you have troubleshot it, thus far
4. Proceed from there as necessary.

Mark the messages as junk. The emails are not connected to any update.
