Love easy questions.
1. You won't get railings to show in 2D. (One more reason Stairmaker should be upgraded or dumped) You'll need to draw the railing yourself, with lines, a fill, or a zero height wall.
2. Open the stair, turn "scale neutral" parameter ON, along with the arrow under that, and turn the separate "Arrow UP/DOWN" parameter OFF. You'll want to turn off "Details". You'll lose the dashed riser lines, though.
