troubleshooting incorrect date values problem

[hsimon46]

Correction -- after restarting the NAS, I'm no longer getting the date-related errors. Thanks!

Last question: I still have about 25 albums that appear not to be tagged properly in any field, which account for ~90% of the remaining log errors. I'd like to correct those too (I assume manually), so I'd be grateful if you could advise on a program I can use to do that, and how I access the metadata on the Synology NAS to make those edits. Thanks again for all your assistance!!
