The L/R orientations that you are using in your schedules are simply telling you which way you placed the window with the last click of the mouse as you choose the window reveal side.
i.e. did you pick to the left side of centre or the right with the last mouse click.
If you want a true opening value then you will need to have it scripted in your window (if it isn't already) to say whether it is fixed or openable or in more detail if it opens on the left or the right or both (or none).
Basically you will need to script into your window a parameter that gives you the output you want.
It could be something that you have to manually input a value yourself (you may as well just add a text field to the schedule and add it there) or you can make the parameter automatic based on the configuration of your window settings - but you will need a knowledge of GDL to do this.
