Many orchids secrete excess sugars this way. If you taste the sap it will be very sweet. Sometimes so much will be produced that it glues the buds shut. It can be gently washed off.
Happens to me too, now and then. It's usually a the tip of the bud, or along the edges. I give them a gentle squeeze to break that seal if they have trouble opening all the way.
