Reimported spotify files not filtering correctly

Due to the recent downtime I reimported spotify data to fill in the blanks under the idea it'd automatically filter however the suggested amount of time for that to take anywhere I've look is significantly less than its already been. I currently have data that shows impossible minutes on many days, which while I have near constant background sound on Spotify, that of course cannot exceed the amount of minutes existing in a day which stats would reflect. I have to assume this isn't the only instance and I do hope there will soon be a fix to this, whether it be improvement in the filtering system or an option to clear all past data before an import in the case of this error happening or to prevent it.
