The same error in several translations (Finnish, Polish, Russian, Swedish) makes Service Manager crash when clicking on the button "Optimize".
Note: I didn't check the Chinese translations. The French and the German translation is OK.
I made a fix for the Swedish translation here.
The translators haven't been aware of some charachters added to the line next to "CJiv75" of the section in the newest English language file.
Indeed at the end of that line the characters "ID||ΓΏ||" were added to add a new column header "ID" to the Service Manager window.
Because those new characters are missing the tool crashes when clicking on the "Optimize" button.
Fixing the issue is simple: add the missing characters where they belong in the language file and save the file.
Maybe the developer should warn the translators when adding such a "pitfall" to the English language file. Being a translator myself I know it's rather difficult to be aware of such small new additions at the end of a line, given the fact that translators rely greatly on their former translation(s) and so miss those new characters.
