Window Mirror Mode commands not working in 4.17

Hi

Just upgraded to 4.17. By default, somehow unreal sets my vive to use WindowMirrorMode=1 and i change it in

project folder → Saved → Config → Windows → Engine.ini

by adding

[SteamVR.Settings]

WindowMirrorMode=2

I have added this in 4.15 and 4.16 and its not working in 4.17. I even tried using it as a console command and it did not work for me. I do restart unreal after I edit the file. Did it change where i need to put this or anything that someone knows of? Thanks in advance for any help!

Got some help going on the forums. Looks like the new spectator mode is replacing the mirror mode commands.
