Villagers/animals/paintings and armour stands disappearing

I don’t really know what version this is but probably 1.18.2 
On Minecraft bedrock edition (Xbox) when we logout/save our world then when we log back on our world. Our Villagers/armour stands/ animals and paintings disappear. This is frustrating and I’m gonna stop playing until this is being fixed. Spend ages to get 20 villagers for a iron farm for it to disappear

 

also don’t have a image to show
