How can I correct the location of a Tablespace Datafile in the pdb

Oracle Database 21c Standard Edition 2 Release 21.0.0.0.0 - Production

Version 21.3.0.0.0

Hello

I wanted to move the sysaux tablespace as per How to Relocate the SYSAUX Tablespace (Doc ID 301186.1)

I used method 2

METHOD 2 (move the datafiles in mount mode)

====================================

1) SHUTDOWN IMMEDIATE

2) Relocate the SYSAUX datafile(s) to the desired location

3) STARTUP MOUNT

4) ALTER DATABASE RENAME FILE

   '/FULL_PATH_OF_OLD_LOCATION/AND_DATAFILE_NAME.DBF'

       TO

   '/FULL_PATH_OF_NEW_LOCATION/AND_DATAFILE_NAME.DBF';

5) ALTER DATABASE OPEN;

The problem is after doing this the CBD reports the correct location NEW of the SYSAUX datafile however the PDB still reports the OLD location of the SYSAUX datafile.
