When I try to put music discs in the jukebox in MCPE, I don't hear the music. Also when you write in the book and quill, pages randomly disappear.

Well I have a few issues to report. First of all, in MCPE, when I try to play music discs in juke boxes, I don't hear the music. Secondly, when I write in books, and I return to them later, some pages of my work are empty. Thirdly, I was returning to my house in survival to get my diamond sword because I was gonna go to the nether. I tried to get my sword out of the item frame but it just disappeared after I got it out. Same thing happens when you break shucker boxes in both game modes. You don't get the shulker box back.... PLEASE FIX THIS!! PLEASE!!!
