Wrong concept answers localization in Create Patient XForm designer

Tested with OpenMRS standalone 1.8.4 downloaded from
http://sourceforge.net/projects/openmrs/files/releases/OpenMRS_1.8.4/openmrs-standalone-1.8.4.zip/download

Tested on both Chrome and Firefox latest versions with Windows 7 and Ubuntu 10.10

XForms module 4.0.9.5

In order to replicate the issue:

Install the starter implementation with MVP/Ciel dictionary
Login as admin/test
Open the Global Properties
Set xforms.usePatientXform to true
Save the new global properties
Customize CIVIL STATUS (1054) concept with STATO CIVILE (Italian)
Customize SEPARATED (1056) concept with SEPARATO
Now both concept have a fully specified name in English and Italian
Set the OpenMRS locale to italian
Go to administration -> patient XForm design
Open the Civil Status text widget on the left of the civil status list box and rename it to "STATO CIVILE".
Go back to concept dictionary and localize another answer to CIVIL STATUS for example MARRIED (5555)in SPOSATO.
Go back to the patient xform designer and expand the CIVIL_STATUS form field with
The SPOSATO localization will not appear in CIVIL_STATUS tree. Instead the non localized version (MARRIED) will show up
