Card number is not read consistently

Hello,
We bought a ZKTeco UHF6-18E-PRO and we encountered some issues with it. We configured it using the demo software and for a single physical card, we get 2 different card numbers. Is there a reason for this? Which of them is the real and actual one and how do we avoid this? Is there some other software or some way we can control it?

=======================================================================

We changed the location of the device and now the tag is always read correctly. Could it be affected by interferences? Is it affected by metals, wires, anything like this?
