End Portal does not appear.

Hello.

Im play to "vanilla" version. I try find with Eye of Ender a End Portal in Creation mode. Then I get into Stronghold the Eye stuck in the middle of stones, in a place there the Portal must be. Im try over 10 times with differens map sids. Same problem in Android version.

Thanks.
