When exporting to USB, phrase is not copied

Scenario: I have 2 computers running rekordbox. One that I use for tagging etc and another that is hooked up to a DDJ-800. On computer #1, I export the playlists I want to USB (in rekordbox). I then plug this into computer #2 and run rekordbox.

Issue: All the metadata shows up except for phrase. The phrase bar is blank.

Is this a bug or by design?
