From documentation :
Disable Internationalization to Use Customized FCCs from Upgraded Agents
Versions Prior to 12.51
The default internationalization support introduced in 12.51
agents prevents customized FCCs created for use with agent
versions prior to 12.51 from working upon upgrade. If you
have upgraded such an agent and want to continue using your
customized FCCs, disable agent internationalization using the
Localization agent configuration parameter.
Important! Disabling agent internationalization prevents the
use of all forms supplied with the new agent and disables all
other agent internationalization features. For a longer term
solution, we recommend migrating your existing FCCs to work on
an internationalized agent and reenabling agent internationalization.
