The issue is not that they are the same directory it is:

FATAL:  database files are incompatible with server
  DETAIL:  The data directory was initialized by PostgreSQL version 13
, which is not compatible with this version 12.14 (Ubuntu
12.14-1.pgdg18.04+1)

Check the value that is the PG_VERSION file in each data directory. It 
should be 12 in /usr/pgdata/pg_data  and 13 in /usr/pgdata/pg_data2.
