The accordian door in our previous TT used to pop out and detach from the post on the wall. The post seemed too small for the hole in the door, and the edge of the accordian door did not sit flush with the wall (one or both was slightly warped). So unscrewed the post a turn or two from the wall so it stuck outfurther, and then I wrapped some electrical tape around the post which made it a much tighter fit in the door latch and it no longer popped out.
I can't say I ever liked the accordian door - it never really provided any privacy or kept out light, since it was a white color. My new TT has black out curtains, which keeps it really dark in the bedroom. Makes it easier to sleep in later. But the curtains don't cut down on sound either. One of the TT models we were looking at had the sliding wood doors, which I would have preferred, but we didn't end up choosing that model for other reasons.
