The Camera Raw editor available in Elements is a "crippled" version of the one available in Photoshop CC. I'm afraid you are not missing anything from Elements. That's the way it comes.
Greg, I just found this... I'm having the same issue in PS cc 2023. The app's fully updated, but I was watching a tutorial and realized that my toolbars across the top or the side are mostly missing. (Like the gradient tool, etc. ) Any idea how to get them reinstated?
Edited, never mind. I just realized they were moved to the sidebar and buried under the masking icon.
