Items missing from chest(s)

Upon logging back in, items are missing from chests. The whole bottom half of a double chest of spider string, Netherite enchanted Pickaxe with Efficiency V, Unbreaking III, Mending, Enchanted Shears Unbreaking III, Two Diamond Enchanted Shovels with Unbreaking III Mending and Efficiency III and V. Very odd, and utterly frustrating. Also to note, I just created this account to log this issue as I do not know the password or login to the account used on the family xbox, so I understand you cannot fix the issue on my bedrock world. But could you please advise if you think this is a beta issue or not? Since signing up to the Beta program it's been nothing but glitches, bugs, lag and inconsistency. Cheers.
