We had this issue on Team 3389 last weekend and it drove me nuts as the programming mentor.
We finally spent a few hours on the phone with NI on Monday and discovered there is a bug in the Smart Dashboard code currently. There are two workarounds, one of which I forget.
The work-around we are using is to shutdown the Dashboard app until AFTER you've deployed your code (via deploy or running from Robot Main.vi)
Since starting to use this work-around we've had no issues. I'm surprised this hasn't made it to an update or official blog post.
Hope this helps,
