Why do screenshots from my Samsung smartphone appear in OneDrive's "Camera Roll" folder?

Why do screenshots from my Samsung smartphone appear in OneDrive's "Camera Roll" folder, as well as in the "Screenshots" folder in OneDrive under "Samsung Gallery"?
Photos taken with the smartphone camera only appear in OneDrive's "Samsung Gallery" folder.

The OneDrive app does not include any "Camera Roll" or "Camera Upload" option in its settings, but the "Camera Upload" option is turned off on all other platforms where I am using OneDrive.

Gallery photos get sync to onedrive so every photo or screen shot you take will also appear there.

Not necessarily.  Theoretically this is controlled by the option "Albums to sync" in the Gallery Sync settings.  Until recently, the only album I had selected was "Camera", and so only my photos were being synced. They appeared under "Samsung Gallery/DCIM/Camera" in the OneDrive pictures folder.  

Because I also wanted my Samsung screenshots in OneDrive, I recently added "Screenshots" to "Albums to sync".  This had the expected effect of syncing my Samsung screenshots with the subfolder "Samsung Gallery/DCIM/Screenshots" in the OneDrive pictures folder. However, it also had the undesired effect of uploading my Samsung screenshots to the subfolder "Camera Roll" in the OneDrive pictures folder. I say "uploading" because the screenshots remain there after I have deleted them from Gallery on my Samsung smartphone. 

Now I have turned off "Screenshots" in "Albums to sync".  As a result, Samsung screenshots are no longer synced with the subfolder "Samsung Gallery/DCIM/Screenshots" in the OneDrive pictures folder. However, they are still being uploaded to the subfolder "Camera Roll" in the OneDrive pictures folder. This result makes no sense to me, but I can live with it.

Hi, What device are you using / seeing this behaviour with?

[rsbrux]

S23 Ultra

P.S. I didn't provide this information in the "Related Products" field of my originla post because it takes a very long time for any related products to be displayed in the dynamic list for picking, and my product, S23 Ultra, seldom appears. More often, only products of the S22 family appear.

I was mistaken about the cause of screenshots being uploaded to Camera Roll.  It now appears that "Media Picker" was responsible.  In fact, it also caused my new photos to be uploaded to Camera Roll. I had inadvertently turned it on, probably in my search for a way to get my screenshots on OneDrive.  After turning it off under Settings - Accounts and backup - Manage accounts - <login for your OneDrive account> - Sync account, the uploads to the Camera Roll folder stopped.

I then reenabled Screenshots in Gallery Sync (Settings - Apps - Gallery - Gallery settings - Sync with OneDrive - Albums to sync).  Now everything is as I wished: photos and screenshots are both synchronized to the appropriate subfolders of Samsung Gallery and no more spurious duplicates appear in Camera Roll.
