'Media not found' in Photos after 5.0.1 update

There are a few empty spaces in Photos that yield 'Media not found' when clicked on. Not sure if media actually disappeared due to the update or if these are remnants of media that were not deleted properly before the update. Advice?

It's the latter based on my observations of the retained file details (except -1x-1 dimensions).

Realise it's advisable to backup prior to updating but would be helpful to have a file count for a quick comparison before/after updating. Available?
