Arduino Nano R/C car radio communication issues

the arduino on the controller is constantly running an old code so when I check the serial monitor it claims that it is "sending joystick data to nrf24_reliable_datagram_server" . this message was from some old code by the dronebot workshop YouTube channel. (it was for dc motors so I abandoned it.) is there any way to stop this rom happening ? and how would I do it. I tried testing some of the other Arduinos that I had and it worked but I could not test the nrfs because the headers are unsoldered (I do not have a solder.)
