Select a photo, zoom to full screen then exit, first and last photos are selected

When I select a single photo, hit my space bar to preview the image, and then navigate to any other photo and then hit escape to go back to the main view (in this case, Essential view), both the first photo I selected and the last photo I viewed are now selected. Seems like a bug. I work a lot in the metadata and I have to then click just the photo I want to edit, which adds another step.
