Hi, I dont have support file yet that would explain why no match.
But on SongKong for Fix Songs to update a MusicBrainz song the song needs to contain the following fields
MB Release Id - this identifies the MusicBrainz Release
MB Track Id - this identifies the track on the Release
MB Recording Id - this identifies the song, remember a song can be on multiple releases. Should only have same recording id if same version of song.
Note only the Guid is stored (dcbbe884-1755-4cab-abd5-f9d5e96588fb) not the full url (https://musicbrainz.org/release/dcbbe884-1755-4cab-abd5-f9d5e96588fb)
For example, these are the urls for the first song on this release (that could be derived from the guids in your files)
Release
https://musicbrainz.org/release/dcbbe884-1755-4cab-abd5-f9d5e96588fb
Track
https://musicbrainz.org/track/07b8cbbc-cdd7-475e-919e-dbeb517beecf
Recording
https://musicbrainz.org/recording/cced9a13-e9a3-4ed0-bc5b-a1546484ec1e
On the MusicBrainz Website on the release page clicking on the title takes us to the MusicBrainz Recording page, you can find the MusicBrainz Track Id by clicking on the Track No column, e,g clicking on track 1 wil redirect to the release page but with the track highlighted, and the trackId is the last part of the Url. But note for this particular release because it has over 100 tracks this messes up the MusicBrainz highlighting so you dont see it, but we do see it for second example below
https://musicbrainz.org/release/dcbbe884-1755-4cab-abd5-f9d5e96588fb/disc/1#07b8cbbc-cdd7-475e-919e-dbeb517beecf
This particular song is only on one release, but the same song can be on multiple releases.
For Example
https://musicbrainz.org/recording/9042d375-7f56-4439-b5e3-bb946757f108
is on many releases, so in each case MB Recording Id will be the same but MB Track Id will differ

https://musicbrainz.org/release/acc0079a-8fb4-4316-90fb-e0b3b4c091f5/disc/1#777311cb-0894-4345-b5d7-ba0beb827a2e
Same applies on Jaikoz but Jaikoz has a separate action for updating already matched songs, Action:Remote Correct:Update Metadata from MusicBrainz
