Sort value conflict for Date filter

[paulM]

I recently discovered the Date.yearOnly.index setting for the tag options - which is great. It's a shame I didn't know about it 10 years ago because date tags for all the files in my library are currently in YYYY format and it's quite a lot of work to retrospectively edit them all to YYYY-MM-DD format. But I had a little experiment with a small number of files and the result was perfect. I have used Album.sortTags for quite some time now and the only problem I had was with those pesky artists who released more than one album per year. And this function sorts out that last niggly problem.

I parked the exercise after that experiment a couple of weeks ago as I am quite busy at the moment. To the best of my knowledge it continues to perform correctly on the limited number of files that have been edited but I have just observed a significant number of "Sort value conflict for Date filter" reports in the log file. I don't know if this is causing problems but I thought I would ask what the issue is before editing any more files into YYYY-MM-DD format.

Are these reports anything to be concerned about?
