So when I'm editing my raw photos, after deleting an image, the next image is displayed, though I cannot edit it in any way without physically clicking on it's thumbnail first. How frustrating when quickly editing and removing bad shots from my collection! Anyone else experiencing this?
I am not sure I understand why your would Edit then delete a photo, except maybe if you decide it is not worth keeping even with edits.
I do not see the same "glitch" happening with my install of Classic 7.3 in Windows.
Can I suggest that you try a different workflow. eg. Use the Reject Flag X on the unwanted file and then move to next with cursor keys. Any, and all, rejected files can be deleted later with one keyboard shortcut.
And a reset of the preferences file can often cure a 'glitch' Resetting Preferences in Lightroom CC/6
