Driver card in wrong card slot

Hello, I sometimes help a well-known from which a small forwarder has. Now I drove again after a longer time. Must have put the driver card in the 2nd shaft at the start of the journey. It was then always the message “driver card invalid”, but at the time I did not know yet that I had put the card wrong. Only after driving about 5 hours later when ejecting it I noticed. Now my question, what is stored on my card now? Can I use the next control get problems?
