Neofinetia falcata leaf damage

[beeu23]

Hello Everyone!
I am a complete beginner in neofinetia but decided to get 2 to try it out after reading about them.
They arrived in great condition one even has a flower spike surprisingly.
I did not remove them from their original pot or anything of the sort, and watered them by misting the moss 2 times so far.
I have had them for just 5 days now, and today I noticed browning of one leaf on both orchids.
They are prox 1.5meters away from the window, and recieve direct sunlight for around 2h a day max.
Not sure if it is a burn or maybe edema from overwatering? Some mist could have gotten on the leaf resulting in this?the moss on top of the pot is completely dry but maybe this led me to overwater?

Thank you in advance for any advice🙏🏼🙏🏼
