Help with a wilsonara hybred

[Paddle_grl]

I have had a Halloween Wilsonara for about 2 years that blooms in the fall. It has been putting out a lot of new bulbs. I decided it was time to split it as it was kind of crowded in the pot. I split it in 2. Each half has two old pseudo bulbs and 1 or 2 new ones. I had read you could do these orchids semi hydroponic so that's how I set them up.
I planted them in the clay balls just like all my other phaps that are happy campers. However, the orchid seems to have stopped taking up water. The bulbs are shriveled. Very shriveled and am concerned.
Normally, I watered them once every two weeks maybe (when they were starting to shrivel.) They were in Bark from the store I bought them from. They would plump up the next day. I have been trying everything. I even set them in water overnight. The roots look great. The older leaves are starting to yellow, but I am sure that's kind of normal.
What am I doing wrong with these orchids that they are not drinking water? Do I need to replant them in bark? Are they just n shock still from being split? I didn't have to cut up any roots to split them, they split pretty good on their own.
Thanks,
Karin
