Because he has the MAHA UI changer addon installed, which is probably conflicting somewhere. I can tell because the Food/Food HQ is not default, which means it's been tinkered with somehow.

Before you start pointing finger at MAHA plugin, I did check his plug in. There is nothing that can potentially conflicting. Most of his stuff is cosmetic layout.
No hard function alteration.
But to make you happy, I removed it also. See video.

hes also missing a couple settings below navmesh

Remove all addons and retest it.

It's not missing anything... It was blurred out so I can type it without clustering.
And it's not that I can't select it. It will reset to "none".
(If you read what I posted, If you have profile (task) defined, in your case (screenshot) you do have it defined) then skill profile selectable and stay.) How about you have profile (task) as "none" and test it - select skill profile (anything) and run it.
It happens when profile (task) is "none", skill profile will not stick. Always reset to "none".
And currently there no way to create profile (task), from front end.

Just to make you happy also,
Re-downloaded everything removed all plugin. << (Timely troubleshoot but just to show)

So here is video... LOL
