Steps to reproduce
Have a world last modified before today.
Click the edit button beside the world on the world selection screen.
Close the world options menu without changing any options.
Observed results
The date displayed for the world updates to today's date and the world moves to the top, even though nothing was changed for the world.
If the steps are repeated on a world modified "today", the world does not move to the top.
Expected results
The date does not change unless a world setting is changed, or the world is entered (the latter being similar to Java Edition behaviour).
the game even if you didnt anything in world edit options it takes it as a modification im not sure but this is related on how MCBE deals with files maybe the game rewrite the options so thats why the world goes up in world list tab
