Welcome to the forums.
I have tested this and am seeing the same thing. The though behind this is that it is similar to a Twitter retweet, having the name at the beginning of the broadcast shows who originally sent the broadcast. You should be able to simply click at the end of the name and then backspace to delete the name before sending the broadcast.
Hope this helps. Let us know if you need any other help.
