This note is listed under P#85a, the general signature type. This is because your note is from prefix IK (no asterisk), and is a common issue note. All common issue notes of the same signature type are just listed under the signature type, because adding each and every prefix would take up too much space. If your note was a rare type (such as a replacement note with an asterisk), it would have its own line. Furthermore, there is no prefix *IK (with asterisk), so your note would be considered a regular note.
Hope this helps!
