Don't worry about the leaf's falling off it's natural especially when re-potted in a different soil. In my experience all the leaf's will fall off. I got really worried but then I saw roots sprouting and soon the leaf's returned.
It is good you mentioned the leaf's falling off as some people will remove the plant and think it's dead. I have a vivarium just filled with plants I am going to use in my future enclosures, and let me tell you all the Scindapis marble queens have doubled. The hen and chick has died out

but the love palms are doing great.
Watering: Water your plant once a week like you would your vivarium. I have left the Scindapis marble queens without water for 3 weeks at a time and they are still doing great. Just remember to place a fertilizer stick into the root part of your plant. Let us know when your Scindapis starts growing all it's leaf's back?
