Shriveling pbulb on Beallara - should I cut the flower stem?

[aqualady]

The older pbulb on my Onc/Odon is shriveling... it doesn't quite look like it's dying, but I'm not sure whether or not to cut the flower stem and try to save the bulb. When I bought it a few weeks ago, the flower stem was in bud, then I repotted it, and ever since, the pbulb has been slowly wrinkling. I know it uses energy to produce the flowers, and I think it may have gone through some shock after the repot. There's a new shoot growing between it an another (plump) pbulb. Please advise... any advice would be much appreciated!
