Missed your reply again, now added filters and then found it.

Yes, the TC should work properly, but unfortunately, it doesn't, My
display is as below:
You can see that the "6" is prefixed and ".1/.2/.3" are part of MAC addresses.

This may not be a display only problem, currently, I am debugging a case where
deleting a single entry from the table makes it go haywire, it deletes
the wrong entry,
the same issue could probably be the reason (not sure though).

$ snmptable -v3 -a MD5 -l authNoPriv localhost -OX -Ci
                        index mpduTx
["wlp1s0"][6:52:54:0:c8:53].1    302
["wlp1s0"][6:52:54:0:c8:53].2    307
["wlp1s0"][6:52:54:0:c8:53].3    328


The MIB entry snippets are as below:
