@Nicholas.
I think you are doing it worng. When using the Hot Cue Bank list you need to load a track above, like you did. Cue the start point you want to save in the Hot Cue Bank list. Once done click in the below section A, B, C.... where you want to save that in the Hot Cue Bank. It is not there automatically as rekordbox don't know which hot cues you want to save in the bank.
