I just ran into this issue and I'm glad you've been responding @DTS Engineer Just filed my own bug report FB22844211 because my brand new Asus monitors (which i purchased after running into the duplicate EDID issue with dual also-brand-new KTC M27P6 monitors) are only allowing one to be detected. Model XG27UCG from asus. Really, really hoping that this gets addressed. I have absolutely loved my M4 Pro Macbook Pro (first mac i've ever owned) as a software engineer.
