Photos will overlay a deleted image on the next or previous image.
Why does the Photos app (Monterey) sometimes overlay an image that has just been deleted?

Hi - Try restarting your mac in safe mode and then trying.
Then restart normally, and try again.
Safe mode will clear temporary files and caches, and sometimes fixes odd glitches such as this.
