Don't worry about the new grows that have failed... once conditions improve, it will very likely pop out some new ones successfully. Watch for signs of rooting (new growth may be an indicator and it may not) and as soon as you see that happening, drop whatever else you may be doing and repot. (C. gutttata, which is half of Wainae Leopard, is rooting now on my two plants. So keep an eye on it)

Thanks for the helpful information! I repotted a few months ago but inadvertently bought orchid bark a size smaller than expected. I ordered some larger bark today and will repot as soon as I see new root growth.

In the meantime, do you suggest cutting away the damage or just leaving it alone?

Unless you see rot spreading down the rhizome toward the rest of the plant, I think you're safe just leaving it alone. It is very likely that there are "eyes" at the base of the new growths that didn't make it, that could be the source of new growths. If you have to cut, the main part of the plant will also most likely have "eyes" to develop into new growths. If the rot looks like it is spreading back toward the rest of the plant than cutting before it gets farther, and dusting the cut with cinnamon (a natural fungicide) would be in order. So for right now, I think just keep an eye on it.
