Missing albums after adding new albums

[chip]

Hi Simon,
I am now even more confused.
I removed the 10 recent albums and 128 tracks.
Now my track count is as expected but the album count is 2 less than before. Still missing 2 albums from before adding the new albums.
I know this because I keep a spreadsheet with the latest additions until I make a full backup. Part of my recovery strategy.
Starting numbers
Albums / Tracks
starting 1958 / 24389
add 10 / 128
results 1966 / 24517 missing 2 / 0
remove 10 / 128
results 1956 / 24389 missing 2 / 0

I will try running a rescan with DEBUG later today to see if that can provide anything meaningful.
Does the DEBUG log mention if an album is merged with another album?

I think the only way to resolve this is to compare the album folders on my QNAP to the albums in MinimServer.
Do you have any other idea?
