I don't know, but I have a good guess. 2-3 years ago, someone tried to
migrate to Mailman 2.1.x and then reversed, but this process left
config.pck files (converted from the 2.0.x config.db files) in some or
all of the lists/<listname>/ directories.

The current list upgrade process is finding those old config.pck files
and using them in preference to the actually more current config.db
files.

Start with your good 2.0.12 installation and remove any config.pck and
config.pck.last files from the lists/listname/ directories and then
follow your upgrade procedure.

Then when you are satisfied with the results, remove the old config.db
and config.db.last files from the new installation so that they can't
be used as fallbacks 2 years from now.

A possibly viable alternative is to look at your 2.1.9 installation and
just remove the config.pck and config.pck.last files from any
lists/listname/ directory that has a config.db. Mailman will then
convert the config.db the first time the list is accessed, and if you
like that, you can then just remove the old config.db* files.
