Keeping/governor

I have the governor and I kegged my beer last.. I tested with soapy water for leaks and couldn't find any.. However I noticed the psi dropped 100-200 psi in an hour.. I turned the tank off as I went to bed. When I got up this morning, the psi on the governor read 1000 psi less.. Am I leaking? Or is it possible that it's a faulty gauge on the governor? I pulled the valve on the governor to reset the keg psi but the tank gauge did not move.. Is this normal?.. What should I do? I haven't heard any leads and at 1000 psi in 8 hours, wouldn't I hear something?

If your tank is sitting in your fridge, the tank pressure reading on the gauge will drop. The tank is fine. It just reads lower when it is cold.
