Good app, but not the best

If you searching for simple app it is. But I found a bug - when you changing your salary - it will be changed for all monthes before too. For statistic its not quite good.
And another one issue - i try to export my data in csv on site(its in russian) but see only ??? characters instead of my comments.
Please fix it ASAP.
