Hello I am from Finland and the reason for the swedish is because Finland was a part of Sweden between 1200-1809.
After independence from Russia in 1917 the country adopted a constitution that made finnish and swedish official languages. Around 1920 11% of the population spoke swedish, today it's dropped to below 6%. Hence most finnish products will tend to have some or a lot of swedish on them. Doesn't mean they were meant for export, but if they were to be exported anywhere Sweden is one of our biggest trading partners, the biggest export country some years.
