Squishy leaf..What's wong??

[Orchid Whisperer]

Erwinia it treatable if it is in the right location on the plant. The original post from March 2011 shows rot in the crown, that is tough to treat, plant loss more likely.

If the rot is away from the crown, cut the leaf off with a sharp sterile blade, cut in healthy tissue outside the infection, you are more likely to save the plant. Keep the plant dry afterward, observe it frequently for possible recurrence.
