While I don't have an answer to this question (sorry, wish I did! :/ ), it seems you're right: after you pointed out that this particular track was missing, I went and doubled checked and searched for it myself, but no luck unfortunately. This just led me to believe that maybe not all of the tracks that were used in the episodes have been fully released yet? (which is a little surprising since this also happens to be the very first track we hear in the whole anime/very first episode) I myself have been particularly searching for the track that was playing in the background when Karasuma-sensei was on surveillance duty and when Bitch-sensei made her walk/appearance during the assembly in episode 5, also the same track from when Koro-sensei revealed the results of the first semester final exams to the class and learn of their scores/ranks and their success in the wager against A class (episode 16). Maybe we'll get these tracks in a second album in which they include the missing portion of the OST? Anyway, I wish I could've been more helpful to you. ^^"
