The setting is saved in my projects. At least it was when I just tested it. I do not vary from "All" normally.
That is very odd. I'm probably overlooking something but if not then something is overriding the behavior you are reporting. I do not recall a preferences option regarding this and AFAIK this project (as most of my projects) are just the standard New Project "Blank" Template... (or whatever the included one is that pops open with no tracks but all the Skylight windows showing... Inspector, Browser, TV, Dock, CV, CB).
Really nothing more than an intellectual exercise to dig into because it of course is not a concern for me. I just like to contemplate (and figure out) the hows and whys just for the sake of knowing... as I assume you do as well.
I might poke at it but I'm still trying to sort out a decent plan for that automation problem I was having... and it wasn't an automation problem actually. It's a "this sound on these instruments at this point is annoying the fruxxor out of me and it needs to be fixed" so automation was the most logical path. Since that wasn't working I'm resoting to the more barbaric methods I usually use. lol
