Hello I'm new here!

I agree with Roberta. If you just repotted a year or so ago, leave it be. From what I can see of the media and roots near the top, they look fine. Don't worry about the leaf that is dying. It's an older leaf, and it's perfectly natural for it to turn to yellow, then brown, and eventually fall off. Let that happen on its own time.

Provide this plant with the proper temps, watering schedule, light, and humidity, and it should do just fine.
