Can somebody point out the mistake in this list?

[RayJason]

I'm currently working on completing ayu's discography on my harddisk, but there is something totally wrong with the order or with the content. I don't know what it is but there is definitely something wrong with this list.
*Sunrise / Sunset ~LOVE is ALL~ is missing, and if I would add it in then "L" (her 50th) single would become her 51st single and HBYA would become her 52nd and that's wrong right?
(I also left out Dream ON and a song is born, since those are collaborations) ~

Singles:



(sorry I PrtScr because I am too lazy to write it all down XD)

Thanks in advance!
