The named Typeterm definition contains a Mapping pagesize setting different than its Device screen size setting, which is often unintentional. See also message TXRB0023W.
The Typeterm entry is not upgraded
Either manually adjust these values in dfhrdef, or run the upgrade process (dfhpcupg) again, specifying /t= (force pagesize = device size) or /td (allow sizes to differ).
