Do not fiddle!. Some will form a sheath and bloom straight away, others will bloom without even forming a sheath, others will form a sheath and do nothing for months and the sheath might even go brown and appear dead.

Do not fiddle, many orchid growers have and have broken off tiny buds.

Thanks Arthurm

Just needed to hear someone else say it. The leaves on this particular plant grow out to a very flat posture. Hopefully, when it has fully opened, the sheath will be able to correct itself. The plant is quite young, so this may be a false sheath anyway. I'll show another pic in a few weeks so all can see what happened.
