It looks like the QuickTune result notification and the information in the QuickTune results don't match!

The QuickTune result notification says, “Extraction quality has improved,” but
but when I click that notification to view the QuickTune results, it says, “No keys with improved accuracy were found.”

Since this seems to happen frequently, it’s hard to tell whether the extraction has actually improved or not.
Please look into this! Thank you :)
