Monster eggs can not be successfully generated

The latest beta in my world, 1.11.0.9! All hostile monster eggs can not be generated, holding the monster egg click on the ground did not respond, the following picture is my new test chart, which is a monster egg that can not be generated! This BUG [features] hope that the official repair as soon as possible!

Sorry, because it is the first feedback problem, there are some places that don't understand, this time in English!
