disappeared mobs that are tamed in bedrock 1.17.41

Dear Mojang team, 

I have a small bug in my bedrock world: mobs that are tamed in bedrock 1.17.41. disappeared.  

After I updated Minecraft on my Xbox I went on my world, after some time I went to my base to see that some of my tamed mobs have disappeared. As not all tamed mobs disappeared I left my world and attempted to make a copy as a backup. As I was waiting for the copy to be made I was kicked out of Minecraft. I went back in to see if the copy was made but instead of saying "Copy of name of world" as it should have said,  it just had the original name of the world.  I didn't know which one was the copy and which one was the original so I opened one of the worlds and I saw that all my tamed mobs had disappeared. 

Could you please support me in recovering my tamed mobs? Is there a way to do it?

 

Thank you for your help!
