Last.Fm doesn't have a full spotify listening history after connecting

[HasDylgato]

Sooo i've had spotify premium for about a year and a half or so, and i just now connected to try and get a full listening history, and it only showed what i had "scrobbled" from 2014 when i originally joined last.fm and what i had listened to after i started "scrobbling." I'll also mention that i've had 2 spotify premium accounts the whole time i've been using it. The one i'm currently using i've had for maybe 8 months(ish), which is all i'm really trying to look up, and is the only account i'm concerned about. The other one was to attached to fb and did not contain my current email and credit card, so i really would just like to see if it's possible to find a full spotify "sccrobbling" history or if there's another way

to look up my full spotify history that also would solve my problems, which from what i've read online they should've been by now. I'd appreciate any help and junk thanks!!!!!
