Why does zero ring the phase in the socket and is it dangerous?

Changed the shield. The situation is this, in two outlets (I did not check it anymore), zero rings on the phase. That is, the multimeter beeps, but at the same time, the machines do not get out and everything works. There was nothing in the sockets. What can it be and is it dangerous?
