Fill them back up, reset TPMS and all OK. To me, the system has been very useful!
The 11mm nut that holds the valve stem to the wheel rim has been known to become loose. GENTLY tighten it up - snug. Its very low torque!! (~4Nm ?) I would also use some soapy water to check the valve stem area for any leaks. IF your tire still leaks air... you might bring your tire to a shop that can put part of the tire under water and check for leaks that way.
