Sats not showing after off time

I was not logged in into stats.fm for some time and it is safe to say that a lot of songs I listened to during that time do not show up in my history. Example: I listened to Bara bada bastu by KAJ all day on tuesday and wednessday and now your app says, that i would have listened to it like 16 times. That is really impossible. How can I fix this? Do I have to request the data from spotify again?

I would be really happy if you would help me out on this.

Kind Regards
