Auto shut off timers with light groups

Hello, All of a sudden I cannot keep my light groups on. For almost a year now I've been able to turn on my kitchen lights with 1 click and they stay on until I turn them off. Now, I only have the option for 30 seconds, 1 minute, and 5 minutes before they auto shut off. I cannot for the life of me figure out why an "always on" option isn't available for a light group. Can someone please shed some light on what I can do? Thank you.
