Engine & Rekordbox library refresh

if you try to refresh Serato library (in Engine) it works, then you drag & drop any Serato playlist in Engine collection keeping any Serato Hot Cues (great feature!)

if you try to refresh Rekordbox library (in Engine) it ask you to choose Rekordbox xml file, you choose it but it say it’s unable to refresh… any STOP on last Rekordbox versions to do that?
