I used a complete copy of the latest vanilla localisation from each language. But yes you are right in terms of old entries. But this is strangely normal and there are lots of unused or old entries still left in Attila from Rome 2. If you want to find my custom added entries, then you need to scroll down to the bottom of the file and at about 90% there is a line called "---> START OF THE UPC" and then comes the first mod AUM-ATT.
