Camera Raw Presets saving incorrectly in 15.0
Presets saved in Camera Raw 15.0 are not preserving the actual data, seemingly at random. For example, I created some presets of some subtle color adjustments for studio work and when applied, the presets are remove all saturation and greatly increase the contrast, rending the images high contrast black and white. Not at all what I need for a project I need to get done — very frustrating. I quite and tried again and found it was changing every parameter under the basic column, even items I didn't adjust.
See below for an example. The settings on the left are what was saved as a preset. The settings on the right are what results. (other paramters are affected too.) They should be identical.
In its current state, this is not at all useful and is an impediment to getting work done. I've downgraded back to Camera Raw 14.5, which exhibits none of these issues, but doesn't like it when I touch the presets I created in 15.
I'm running a 2020 iMac 5K with OS 12.6 and 64GB of ram. Photoshop 2023 with Camera Raw 15.
