Missing column info after file transfer to NAS

[Uncle Bob]

Hi folks.
Been using MMW5 for a while now and really pleased with it as an alternative to iTunes.
To make some space on my PC hard drive I transferred my music collection to my NAS drive, cleared the old MMW5 database and re-scanned the new file location on the NAS.
All went well...apart from the fact that there is no longer any data displayed in the Album Artist column. It was displayed when I had the files on my PC but now not from the NAS. I have checked the file properties and the data is still there.
Any help would be appreciated. Thanks.

Which Build (Help > About) of MediaMonkey, and what File Type(s) is this the case for?

How did you verify that the Album Artist is actually present in the file tags?

Hi, it's 5.0.5.2995
They are mostly mp3, with a few flac and m4a files.
The file properties show the data in the details tab

So, the data is there, just the column is missing? In that case you can enable the Album Artist column.

Sorry, the column isn't missing, the data in the column isn't displayed. The column is blank.

The file properties show the data in the details tab

seems to contradict

the data in the column isn't displayed

Where have you confirmed that the Album Artist tag is actually saved in the file tags?
