New Burr orchid with spots?

[hypersparkle]

I picked up a few new orchids recently including this lovely Burr. orchid and today I decided to repot early (still in bloom) because I am the worst at watering with moss and wanted to switch it to some oncidium potting mix. When I got to work on it, I noticed that it had some spots, that when light shines on them are see through.. :/

Thoughts? It had a leaf already go yellow/brown (see an earlier post). Roots looked good.

Here's a link to some photos.
