HDR Resetting white point values on restart

Hello. Every time (I think, it might be more often) I restart the game, the HDR is set to at least 1000 nits as far as I can tell. My monitor only goes up to 400/ 600 depending on the setting and bright areas are wildly clipped either way. Once I go back in to setting and tweak the white point back down to 400, everything is fine and looks great. But having to reset it every time I launch is not ideal. Thanks!
