Album Not Showing All The Tracks

[IdrisRoberts]

Flac Album created (20 tracks, Compilation Album). Metadata on all tracks completed using Mp3tag. Names , album name, compilation tag checked, art work done.
Using Perfect Tunes everything appears correct. Album is copied onto my Synology NAS as usual. When I go to access the music only 5 of the original 20 songs are there.
I have re-done all metadata (using Perfect Tunes this time) and still the same problem.
This is the first time this has happened (I Have in excess of 1500 albums and all are OK)
The only thing which is different is I updated Asset UpnP to latest Version R2024-08-07 I wouldn't have thought that this would have affected the metadata.
Any help would be appreciated.

Disc number is the same for all tracks?

Album name is identical?

Compilation tag is set to 1 for all tracks?

Yes to all your questions. I have completely redone album again from original audio files. Changed from Wav to flac using dbpoweramp, completed metadata using mp3Tag, checked again with perfectTunes. All tracks show as being correct (20 Tracks) Copied folder to my Synology NAS, allowed asset to rescan, used my usual control point to access the folder (mconnect) now there are only 3 songs showing!!
I have cleared the database and am allowing Asset to do a full scan from scratch to see if that works.

Just finished full rescan from a cleared database. Checked and all songs are now showing!!
Strange that, usually adding to the database does not require a full rescan to show correct info. Is it possible a glitch in version R2024-08-07 or just the vagaries of metadata editing ha!
Thanks for your input.

It could be when you first added the album it was split, then remained split despite editing. A full rescan is good in such circumstances.
