Help with Test Mode Smart Dashboard

Hi, my team has been using smart dashboard to use sliders for testing motors. We code in java. While in test mode, the talons connected are shown, but at random will disappear upon a new launch. Sometimes only a few talons are shown, or none at all. It seems to be completely random, as no talons are disconnected, and even upon the same relaunch of code different talons appear. Does anyone know the cause for this, or a way to resolve this issue?
