Minecarts with hoppers disapears randomly

I have a problem with minecarts on my autofarma which are randomly disapearing. Sometimes when i reload world, sometimes when i go not so far away from chunk where minecarts are. I constantly need to craft new ones and put it on rails.

The problem was on xbox one x and now is on xbox series x. On PC appears too.

Maybe Rails are between chunks but on xbox there is no way to easy check where the chunks are..
