Glowing control

On the control panel, pots,pans, normal wash and china gentle buttons glow that is they are not lit and do seem to function They do lite up when selected, but the have a constant little illumination at the center bottom on the button. Is this a problem? is it going to be a problem. Warranty on this unit is up in one month.We have not noticed this before. Anyone ever encounterd this?

I would call for service and have it repaired well it’s still under warranty.
