Yes, I too have encountered this bug when trying to delete an e-mail address in my contacts list.
I reported this as a bug in a recent post to AppleVis and also wrote to the Apple Accessibility support about it.
In addition, I was not able to even delete an unwanted e-mail by editing the information for a contact by double tapping the "delete" button associated with a particular e-mail. I have also reported this here and to Apple.
I am using iOS 8.3 on an iPhone 6.
