It looks like the regulator with the two gages has been set at some outlet pressure for a long time, with the outlet plugged, and it leaked through the regulator just enough to overpressurize the outlet pressure gage. The gage may still go back to zero when the presssure is relieved.
Relieve it by unscrewing the adjustment handle on the regulator - turn it counterclockwise, until it feels loose. Then crack open the fitting that must be sealing the outlet. Or, shutoff the valve on the CO2 tank, and loosen that fitting to bleed off the trapped gas.
You got a great buy there if you paid $50 or so. Maybe even more.
