Please do not ignore me again and again

Hi

Please please please please listen to me just a bit. What if I have right? Please just give me a chance.

First of all THANK you so so much the new update, we love it  Dolphins, and fishes...now we kan build under the water glass castle. Awesome.

 

My problem: Please help me fix this.
We got the 1.4 update, which fix my last problem. I got back my world. I did not do anything, I want to delete it /because you said/ and before I delete I just want to see one more time.
And it is back. here is the video AFTER 1.4 update : https://youtu.be/MGQMbw-WH5M

Here is the old video BEFORE 1.4 update :  https://youtu.be/AKQy7PC6psA

This shows the save data do not have problem.

Question: What should I have to do now? I do not want to lost again my world.

Can you check my save file? I did not play with that. I did only what you see on the video and exit without save /xbox button - manage game - exit/
