lfGlobalMessage () not working when editing fix version

[Elena]

Hi,
When editing the Fix Version field, we need to see the message and change the values of other fields. All changes are indicated in the force sil script. The display of the message is configured with lfGlobalMessage().
In our case, the values of other fields change, but the message does not crash to the screen. To test the script, I removed all the conditions and left only the line with the message.
Any idea why there is no message and how to fix it?
