If you open the .miz file you'll see that this mission in particular has a bunch of folders and files, for example server.lua file in it so you custom view won't work. Don't know why this one has those folders, perhaps it has an introductory track. The options you keep if you have checked "keep these settings for all missions" are not those you mention, because those are really tweaks, not gameplay options. You can try to change the server.lua inside the .miz, or even delete it. Don't know that kind of missions, never seen anyone equal.
