Earlier today I was about to send a text message (well, iMessage) when I received one at the same time. The one being sent seemed to have stalled though I didn't get that red exclamation point. I then had to resend the message but not from the message thread I previously started. I noticed the original one I tried to send is still there but now it appears as "Unknown" with no message body. I repeatedly tried to delete it but it keeps returning. I clicked "edit" and deleted the actual thread of the message (person addressed to) and then delete message itself. Still no luck. Message keeps reappearing as "Unknown" with no message body. I have tried to delete it again with no success.

I've done the following:

1. Restarted Iphone several times. Both after deleting message and not deleting

2. Turned off iMessage and then turned it back on

It does not seem to be effecting anything with the actual use of the app, but it is really annoying seeing "Unknown" and a blank message there every time I open the app. Searching the apple site and google hasn't given me any leads unless I am not hitting the keywords? Please help!! Thanks!
