Items disappear in chest and enchantments are not working properly

I'm playing on the bedrock beta and I have been experiencing a lot of bugs the biggest of which is when I put something in a chest it either disappears or reduces in number for example my stack of arrows turned to one and I have lost countless enchanted items and even ancient debris. I'm certain they disappeared as I put them in a chest with nothing else in it.  Also I went to merge two enchanted bows together when I did I so not all the enchantments carried over but it did fix the durability and I was only addin flame infinity and power the power didn't go on the bow. I've also experienced smaller bugs like a mysterious item in my inventory called "nature" the text on the main menu is different font and my sword is cut in half when I'm in a nether portal. Thanks
