HDR footage blown out in Final Cut Pro. No option to convert to HLG to REC 709

Thanks, I am able to switch the project format to Wide Gamut HDR but after doing that, the HDR clips are displaying correctly but now the regular clips are all darkened and muted. And when I turn up the exposure manually it introduces noise. Is there a way to mass-fix the dark and light clips to have them around the same exposure? Or is it just due to the incompatible standard clips being in a now HDR project?

I tried that, and adding the HDR tools in 709 project setting. The HDR clips are unusable in a 709 project, they're baked in. Even the HDR tools filter doesn't fix them it just dims them a bit. Now that the project is set to HDR 2100 the HDR clips are great but the regular clips are darker. But it's progress. I'll look into updating but don't want the current state to be affected by an update mid project.

Reply edited for correct screenshot

My 2 video clip formats are Rec 709 (gopro) and Rec 2020 HLG (iphone). The encoding options are as shown.

Ok here it is.

Just don't want an update to mess up any of the files.
