I cannot delete iPhone keyboard shortcuts. They keep restoring.

I have deleted old keyboard shortcuts that were no longer used and added new ones using the same shortcut. For instance typing "eml" would auto-fill with my old email address. I deleted this shortcut and made a new one - "eml" = new email address. iCloud keeps restoring the old shortcuts, so now I have two "eml" shortcuts with two different email addresses. Also, old shortcuts are constantly being restored! I cannot delete any shortcut! They will delete for a couple of days and then they are "restored" to my iPhone. How the heck do you permanently delete keyboard shortcuts in iOS? I tried turning off backup, deleting, turning on, waiting, updating to no avail. Is there a way to completely wipe the backup/settings file stored in iCloud for an iOS device?
