Command auto Fill doesn't work

When I try to Auto Fill commands like / give or any other commands it doesn't work

I tried this on experimental and vanilla the problem is still there I tried to restart my console 

But in the end it won't work

On switch I have to move my d pad left to go down right to go up but it doesn't work now

I was on mobile so I just uploaded it to YouTube on a private video If you don't expect this tell me https://youtu.be/sBVYiYOOkbs?si=zU-Ld3AMLaqALtx5

How to replicate
