iPhone 14.5 beta 7. Big Sur Image Capture won't delete photos from iPhone

Imported photos onto Big Sur using Image Capture.
Selected all photos and told it to delete.
Looks like it works - reports no photos in Image Capture.

However, NONE of the photos were removed from the phone.
Unplugging and replugging in the phone makes the photos re-appear within Image Capture.

I don't see a way to erase all photos from the iPhone.
