paph question -what to do with dead bud?

Hello,
I have two paph. armeniacum plants. They both started to grow the buds. One is fine, grows ok and I might even post bloom picture soon(hopefully). Here it is now:



The bud on the other stopped growing while still inside the leaf and now got soft and brown:



I am not sure if it is rotting or drying. How to remove it without damaging plant? There are two offshots on the plant that should make new fans, I am afraid to kill it all.
Thank you.
