Well yeah, the last 2.2.x release was 7 years ago .....

Item data in 3.4.x and above is no longer stored in the MARC but in
the items table, did you run the script to tidy that up?

from the INSTALL file

Koha 3.4.x or later  no longer stores items in biblio records.
If you are upgrading from an older version ou will need to do the
following two steps, they can take a long time (several hours) to
complete for large databases

 misc/maintenance/remove_items_from_biblioitems.pl --run
 misc/migration_tools/rebuild_zebra.pl -b -r

I would back up the db, and try this
