confirmed, but the up-down hotkeys are working fine.
No problems for me after removing those keybinding found on Keyboard tab.
I am suggesting changing behavior a bit. Right now I have horizontal split and upper half has vertical split (all together 3 panes). 1 - top right, 2 - top left, 3 - bottom. Now if I am in 1 and go to 3 and I want to go up I get to 2. It's quite nice if you are shifting your work between 3 and 2 using up/down key combinations. But if I am doing shifting work frequently with 1 and 3 it's a bit more complicated, you still have to go though 2. I would like iTerm2 to remember in which pane I was in. So if I go up and I have two panes, I would go the one which I was before. In my case to 1, not to 2. I had been in 2 and went to 3 and going up again would lead me to 2. I hope you got it :)
