Windows 10 1.14 world corruption

Me and my girlfriend have a survival world we have spent over 100 hours on since August but on the Friday after the buzzy bees update came out, when starting up the world I got a message claiming the world file had corrupted. I closed minecraft and opened up again and managed to start up the world. upon playing I noticed that chunks of the world were missing and some chunks reverted to how it appeared before changing the land. I decided to make a new survival world thinking it was a one off but the same thing happened except it didn't display the world corruption message. I'm not sure what has caused this but it hasn't happened on any creative worlds I have. I can only attach the new world files but the first world has identical issues. Below are screen caps of both worlds. As far as I know, this bug hasn't been experienced on Xbox one or Mobile, only on the Windows 10 edition, I may be wrong though.
