If you squeeze the bulb hard enough, is it really soft? Is there any kind of juice coming out of that pseudobulb? Is there a really sweet smell emanating from the place you squeezed? If so, what you are describing is rot.
Usually old Bulbophyllum bulbs will desiccate as it transfers its energy resources to the newer bulbs. Healthy older bulbs do not usually just mush out. They usually shrivel up and become dry.
By the way, some Bulbophyllum can take quite a bit of light depending on what kinds of hybrids or species they are. Some Bulbophyllum can handle indirect moderately bright light without a problem.
I don't know what your lighting situation for your Bulbophyllum Elizabeth Ann Buckleberry is, but I believe it is one of those Bulbophyllum that can handle moderately bright indirect lighting pretty well.
Many Bulbophyllum love good air circulation around the roots. They also like a descent amount of humidity.
I will also mention that if they are grown mounted, they can be watered far more and rotting would be much less of an issue.
