STIG password FUNCTION not working

Hello All,

Question, the new oracle stig requires 8 characters to be changed. I cant get the oracle supplied function to enforce the rule or a modified function. Where am I going wrong.

Oracle 19.14 on linux redhat 7

alter user DAVE_TESTER profile USER_PROF ;

--PROFILE LIMIT--

PROFILE  | RESOURCE_NAME        |LIMIT

USER_PROF | PASSWORD_VERIFY_FUNCTION |ORA12C_STIG_VERIFY_FUNCTION

--PROFILE--

DAVE_TESTER | USER_PROF

--Should require 8 characters

SQL> alter user DAVE_TESTER identified by "PleseCHanMe_1_2";

User altered.

--only changed 1

SQL> alter user DAVE_TESTER identified by "PleSeCHanMe_1_2";

User altered.

--Tested a different function

alter user DAVE_TESTER profile PASS_FUN_PROF;
