Sideways dodge jumping works great ..... but i dont know how to do wall jumping, i jump into vertical cobblestone and jump again and, nothing.

Same with double jump i dont understand how it works, i push jump in midair and nothing happens

I checked your coros website as well

And the Z keybinding is not on the key controls.

Also this page does not document any blocks being added, but theres a red recharge block and a yellow block being added and i dont know how to disable them.

The features between old versions and 1.12.2 versions are very different, see the curse page on latest info: https://minecraft.curseforge.com/projects/move-plus

Basically all the features you're having issues with dont exist in the 1.12 version.
