Changing validation preference (i.e. Relational) forces a re-build but validation does not pick up changed preference

While adding/testing new validation rules and validation preferences it became apparent that there is a timing/event issue with changing preferences and the auto-build that's kicked off when user APPLY's or hits OK

1) Create simple relational model with table and one column with datatype decimal with "0" precision
2) Saving/validation should result in "Missing or invalid precision" WARNING
3) Edit Preferences > TEiid Designer > Validation and open "Relational" tab.
4) Change the "Missing precision property on columns with numeric types:" value to "ERROR"
5) Hit OK
6) Choose YES to FULL REBUILD
7) ERROR is not created in problems view

I Stepped through this in DEBUG and the ERROR DID get created. Seems the validation preference is NOT getting set/changed prior the the validation logic requesting current value.
