I think the text mean nothing

This Nightjet drives from Salzburg to Venezia Mestre.
The Interrail reservation are unfortunately fully booked. That‘s why I have to make the reservation through the ÖBB website. However, whenever I try to make a reservation online the website says „No tickets available“(slide 2). Although the „ÖBB Live tool“ (a website made by ÖBB, where you can check the occupancy rate of a specific train) says there are still seats available(slide 1). This means that either the train still has capacity and a seat can maybe be booked by calling the service line or the train is full and I am wasting time. BUT NOW HERE COMES THE CATCH, I did some digging and on the official ÖBB website it says that Nightjet tickets come with a seat reservation included (a so called IRT), as seen in slide 3.

So I wanna ask the big question:

What is the best thing to do in this situation.
