When choosing 'no comments' I still count them, but they shouldn't get translated and should be deleted. I'll check into this. Are the file comments actually translated in the output files?
The message 'Language pair is incorrect' is because the input file text did not qualify as Russian nor Ukrainian. I'll have to make a change concerning that message.
I would like to have the original Russian version of the file.
I appreciate the feedback.
I have made some changes to purge these quirks. Will release new versions soon.
