MPC Video Renderer "ruins" HDR in 16.4.5

Please excuse my english, and noob skills explaing my issue, but here we go

HDR doesn't work out of the box, with 16.4.5 compared to 16.4.0, because of the new setting under HDR. See pics.
This because, with 16.4.5, it's not possible to save the settings in "Auto Display HDR On/Off".
It always reverts to "not used" the next time you open MPC HC.
So you need to change manually to "always used", everytime you play a mkv with HDR support for example.

I rolled back to 16.4.0 where it works flawlessly, with just the option "on/off". (not the three "not used" / "used for fullscreen" / "always used" options)

Will be fixed in next update.
