Hello again Nikki!
Absolutely no problem. Unfortunately, the other specialisations do not offer Dutch as a subject. If you choose to specialise on languages, you also only choose one of the three: Either Dutch, German or Spanish, not all three. Saxion also offers Dutch courses outside the regular programme. You can find more information on that here: https://www.saxion.edu/studying-in-the-netherlands/services/learn-dutch.
Hope this helps! :)
