Make a copy of your properties file. For example 'Scramble_ru.properties.bak'. Then try to rename it as follows:
'Scramble.properties'. At this point your briefing should appear, but when you will return into FMB and make any other changes, they save themselves into 'Scramble_ru.properties', so you must do all this any time you will make any change.

I hope this help you.
