Hello! I was accepted with a partial tuition waiver (2/3), but I only have the 2019 application option (no 2019 fellowship option) under the "2019, Master's Degree, International Relations". The final portal (after you click the 2019 application) has a status update link which then takes you to the offer and scholarship info. There is also a link to reply to the offer of admission. So I am not sure what the "2019 fellowships" would mean in your case, but I'll be keeping my fingers crossed for you!
