Floodlight does not stay on

The floodlights on all my Floodligh Cams do not stay on after I turned them on using either the light I can’t in the camera view or in Lights menu and the lights group. They stay on for a short amount of time and then I find them off again. And this is despite me checking that I have selected "Activate until I turn them off"!How do I get them to stay on permanently or at least until the next day when the sun is up?
