Sport mode button not popping up on dash

[mk8_matt]

Hi everyone, on my 2020 Ford fiesta st line edition, I have the sport mode button next to the handbrake, however when pressed, the eco and normal mode only pop up on the dash, no sport mode option to be seen. I have had this problem for a while now, sport mode has never worked since picking up the car. Any suggestions? Has anyone had this issue before? I would appreciate responses. Many thanks
