Can't add/update track durations

[hardbop-man]

I have most of my collection in FLAC. A lot of my albums doesn't have the track duration. I have been told that this could be fixed by going to Record properties -> Misc -> Album path -> Change

When I execute this command on one album there's no track durations added at all. The Play / Cueue function is now visible but nothing more.

Is there a way to add track durations at a later stage?

I don't have any FLAC files, so I'm not sure how OCD handles them. However you can add durations manually easily enough - it's just a bit tedious! Just open an album's 'properties', go to the 'Tracks' tab and highlight the relevant track. Then you can edit duration in the 'Length' box at the bottom right. You can also do this by going to an individual track's 'properties' and edit similarly in the 'General' tab.
