Camera Raw 15.5.1 opens raw photos in two batches when "All" is selected for editing

[1eekeek]

I am selecting all the photos in Camera Raw for editing.  The files are all in the same folder and come from two differnet camera.  Camera Raw opens the files in two different batches. I need to color balance and fix exposure them all at the same time.  I have updated all software to the current verion and I am operating on the latest Mac Book Pro 14 in 2023 Apple M2 Pro Max 64 gb memory MAC OS 13.5.2

How many files are open in camera raw?

What cameras are the files from?

Does the number of files make any difference?

You can reset the camera preferences and see if that makes a difference:

• Hold down the Command key and select Photoshop > Preferences > Camera Raw (macOS) or hold down the Ctrl key and select Edit > Preferences > Camera Raw (Windows).

• Click Yes in the dialog that asks "Delete the Camera Raw Preferences?"

Have any of the those camera raw files had Enhance used on them?
