Missing streams and songs

Hello, Spotify Stats Team.

I wish to report a bug that has occurred multiple times and which was not fixed whatsoever. Basically, my streams are incorrect. There are many songs simply gone from my streaming stats even though they were there before. It even shows in numbered categories - there are some simply missing. In the attached files, there will be proof of my words in the form of screenshots.

I wish for You to be able to fix this as soon as possible. I really enjoy this app- I've been registered in it even before the time of registers were being tracked.
