Problems with my Phals and Cattleya

[cherylsoh]

Hi seniors out there.. I’m new to growing orchid and I have problems with my phals and cattleya. Firstly, my phals were exposed to the direct sun few weeks back and then it caused damages to the leaves. I’m wondering if I should cut off the entire leaf?
Secondly, I have no idea what is happening to my cattleya that caused the leaves to behaving that way.. it was in bark medium. Their pictures are as attached.. please advise.. thanks a lot!!!

I also got the bad experience looks very ugly if you want to cut go on or just live it alone.
No photos has been attached.

The sunburn is done. As the damage did not include exposure of internal tissues, the likelihood of a secondary infection is nil.

Those parchment-like areas will eventually crumble and anything separated from the "base" of the plant by those burned areas will die. I would not remove undamaged tissue, even if there will be a hole in the leaf - if it is still green, it's still creating resources for the plant. However, it looks like that leaf was damaged all the way across, so I'd cut a straight line across the burned area.
