Mobs are spawning on fence gates...

Issue still present in 1.2.3
Will try that, already did the first part, but never with 2 blocks underneath the door.
Thanks for letting me know!
Update: It worked, thank you very much!
@Jonathan Long, that's exactly what happened here, playing on a Realm. Door disappeared after using it and now I can't place it back. Weirdly though, all other doors I have in my world don't have this problem.
This Bug is in the Bedrock Version in Build 1.2.0.20
Having the same Problem, whenever I download a copy of my Realm, the player data seems to be outdated.
