Duplicate streams

Because of the recent issues of streams not being recorded in decided to import my Spotify data again.

But i realised that this caused lots of streams to be duplicated, so I deleted the imported files for now.

Is there a way to avoid this happening?

If not then is the issue with stream count gonna be fixed to fill in the empty gaps?

(Pictures shows that I listened for 33 hours and 44 minutes in a single day)
