If you use main hand left you can´t use any item like sword or lingering poition or something else/ you cant change from left to right main hand

What I expected to happen was that i can use the item like main hand right/ you can change them

What actually happened was i could not hunt a cow or shoot an spectral bow (other arrows i diddnt use) then i tried the poitons but it also don´t work

1. start minecraft
2. create a new world
3.go into the options

5.main hand:left
6. use an bow
7. use a poiton
