Problem with Reefbreeders light

I have loved my reefbreefers light but all of a sudden, I keep trying to change my custom lights and when I do it will stay the way I set them for like a week but then after that week it will go back to the settings I had before. I sometimes don't catch it for a day or two so it has to be messing with my corals. Does anyone know how to fix this or have a problem similar? I am using the one hour custom settings.
