Can't rename values in a Pick List (Incident - Additional Fields)

Can't rename values in a Pick List (Incident - Additional Fields)

Hi all.
On our installation of SDP (9235), we have 2 pick list in the "Incident - Additional fields" area. In the first one, we have some values (Company Names). Now we need to rename two companies, by inserting "OLD_" before the name. I have changed the two companies and I have clicked on the Update button, but one of these don't change.

In the System Log Message I have this message:

field name - CdC
 field type - Pick List
 description - Centro di costo di attribuzione del lavoro
 updated.

Module : Admin
Sub Module : Incident - Additional Fileds
Type : Info
Action : Update
Occurred At : 12/01/2017 12:25


java.lang.Exception: Module 'Request Custom Fields' is not found.

Can anyone tell me why this happens and if I can intervene directly via SQL?
