I use Rosegarden and it seems to like using TENOR clef for Piano parts that don't have their left and right hand parts in separate MIDI channels.
In Rosegarden, you click on the clef you don't want to select it and then go to the Edit menu and select Clef Change.
Perhaps your program has a similar feature.
