Hi @lizzykincaide, leaf drop in these plants can be a symptom of overwatering. Just water when the compost feels dry down to the first knuckle on your index finger, then water it thoroughly and let the pot drain fully before replacing it in its covering pot. I also mist my plant daily as it enjoys high humidity. Your plant looks quite healthy apart from a couple of leaves - don't worry about the newly emerging top leaf, that's how they look until the chlorophyll develops fully. I know it's a bit disconcerting seeing those brown spots but they will soon fade. These plants can be a bit fickle, they like good levels of light but not direct sun. You have done the right thing keeping it away from draughts. In winter it is common for a couple of leaves to drop as light levels reduce, so this and perhaps overwatering could explain your leaf drop. I hope this helps.
