So this has happened in the 1.14.0.4 and the most recent 1.14.0.6 Beta of the Xbox One Bedrock Edition.  I will enter my Minecraft home and use my door, then suddenly I will end up in my basement.  The ground floor of my house and my basement have identical dimensions in length and width which I think may be contributing to the glitch, as well as having stone slabs as a floor mat leading to my front door (to prevent zombies from breaking in).

I do have a video clip of this happening and will try to upload the glitch, otherwise my gamertag is Rdy4fn13 and I can share it over Xbox Live.

Thanks!
