There are some infections that spread through the rhizome, but this sounds like normal senescence. It’s to be expected that the old pseudobulbs will die, particularly if the divisions were only one or a few growths—all the energy has gone into making new pseudobulbs. Unless you see evidence that new growth is affected, I would just pull off the dead pseudobulb but would not repot.
