Custom Authentication in 4.2 will not save Authentication Function Name

Question

Upgrade from 4.0 to 4.2.
When creating a new Custom Authentication the Authentication Function Name will not save in the Apex Create\Edit screen. After the Apply Changes button is clicked and the authentication scheme reopened - the Authentication Function Name will be cleared. If PL/SQL code was populated in the source field - it will still be present.
Looking in the WWV_FLOW_AUTHENTICATIONS table - a new record is created but attribute_03 (this seems be where the Function Name is stored) attribute_05 and attribute_15 are null. The PL/SQL entered in Apex is there in the PLSQL_CODE field.
All preexisting Custom Authentications that existed - there fields are populated and still work correctly. However, if you edit the Authentication Scheme in Apex it nulls out those fields in the WWV_FLOW_AUTHENTICATIONS table and the scheme no longer works.
I can manually set attribute_03 to my function name, and attribute_05 to 'N' in the WWV_FLOW_AUTHENTICATIONS table and the Authentication scheme will work as long as you never try to edit it and save inside APEX( these fields are nulled out if you do this).
Also - Authorizations schemes are behaving similarly.
Checking the WWV_FLOW_SECURITY_SCHEMES table - attribute_01 is always NULL.
No error is ever given inside the Apex designer.
Any ideas how I can debug this?

That's what happens when you don't pay attention to what you are typing (me that is). Edited original post.
DB version is 10.2.0.4.0 (11.5.10 is our ebiz version)
The PL_SQL column in WWV_FLOW_AUTHENTICATIONS is a CLOB. Looking at a a data view in Toad it abbreviates the field to say(HUGECLOB).
This does not occur on apex.oracle.com and all of our 4.0 installs still behave as expected. The DBA said that he checked the install logs and did not see anyting out of order. I've never done an APEX install, is there a specific log file (or naming convention for a logfile) that I can tell him to look in or look for?
