The New Beta feature of minecraft pocket or bedrock edition has a bug with tick speed

In the new snapshot or beta feature of caves and cliffs(1.17),They mentioned that the blocks(copper ones) won't change even if the tick speed changes.But,There is a bug which does not update the ticks in survival,I have created a minecraft world in the newest beta version I have planted some crops,chopped some trees,made a snowman,etc. Due to the bug in the version the crops won't grow,the leaves of trees won't decay,snowman doesn't leave a snow trail when walking please fix this feature I don't want to lose my world,please observe the time in the attached file below the leaves won't decay even after 10 mins in pure survival world
Thank you.

Device I am using to play minecraft with:- Android Mobile(Vivo)
