Question Mark in Fetch New Data

For the last few weeks, I have seen something interesting in the Fetch My Data section of Settings (Settings -> Mail, Contacts, Calendars -> Fetch New Data). If you look at the picture below you will see what I am referring to -

Basically it is a question mark in Fetch New Data, labeled as Mail, but does not connect to anything. I removed all accounts in Mail, Contacts, Calendars, so nothing is lingering. I have looked at every app to see if something would have been created by an app. Still did not see anything. I do not want to erase my entire iPhone and reinstall all the apps just to have this go away.

Has anyone ever experienced this, and does anyone know how to remove it without doing a wipe clean, start from scratch solution? Oh, and FYI - I have already tried Reset All Settings. Didn't make a difference.

Thanks.
