foremost, i apologize for my recent mistake: i've uploaded a new plugin version some days ago (and deleted the previous version both from the server and from my PC), which i thought was stable, but it turned out to be very buggy. so, i've had to re-upload the most recent version i could find, which was
more or less stable. excuse me. all i can do now is advise you to try one of the very old, stable versions.
for example, you can try this version from 06/26/2023:
https://www.mediafire.com/file/cwwtzg1bmy532j6/mb_TagTools_2023-06-26.zip/fileit's stable, but very old.
also, you can try this recent version from 11/04/2023 (but
only if you use
win 10/11 (edited: i saw that you are on win 11) and screen
dpi at 100%):
https://www.mediafire.com/file/h2t08o9562efboi/mb_TagTools_latest.zip/filei'll upload a new, fixed, stable, and greatly improved version in a few days. maybe in a couple of weeks.
but maybe you are using the stable version (it depends on when you downloaded it).
-------------
about your issues:
1. seems to be a bug. i'll check this out. also, maybe it's a bug, which has been fixed already.
2. saving grouping fields to tags is disabled intentionally, just because all grouping fields are already some MB tags. why do you want to save grouping fields as tags?
3. there have been many plugin versions that exposed different LR behaviors (btw, no ALR has been available for a long time; it's been merged with LR. which plugin version are you using?). but i'm doubtful that the version you are using saves some "individual calculated tags." all i can suggest is that recent plugin versions take into account the tags of
displayed tracks only (they
may be filtered somehow, and you may see
not all tracks of your library in the current view) for
displaying/exporting LR reports, but
all tracks, which have
the same grouping tags as the currently displayed tracks for
saving functions. this is quite different (and reasonable) behavior.
if you want to experience the same LR behavior for displayed reports and saved functions,
don't filter displayed track list (e.g.
don't generate reports for
playlists, only for
entire library).---------------------
EDIT:
you might want to try the following latest version if you are mostly interested in LR. this version must be stable, but it's incomplete.
don't use the following commands with this version: MSR, both re-encode tag commands and tag history.
swap tags, save last skipped date dialog, and both settings windows may look ugly, but they must work.
