This is a common issue when there is corrosion built up on the brake output pin of the 7-way. What this does is cause the controller to sense a slight amperage draw which confuses it into thinking a trailer is connected. The other thing you can try is unplugging the controller and plugging it back in. Sometimes the Curt controllers just need to have a hard reset to function normally.

Brake controllers are designed to be on all the time and leaving yours on would not be an issue at all. The reason you don't want to cut power to the controller is that you'd lose all your settings if you did so.
