Zwave lock problems all of a sudden

Locks in Unknown Status

I have been playing with various models of Zwave SmartLocks (Kwikset). For the most part, they work well. Occasionally, they will go into “unknown” state in the ST Smart Lock app. Once this happens, they show as “unlocked” in the ST device screen even if locked. Control of the locks does not work at this point. Manually moving the locking bolt with cause the status to update and everything is fine at that point. Happens about 1-2 a day while I have been testing them out. Ideas?
