Rekordbox failed to export for track which no longer exists

Hey, so firstly sorry if this is a known issue, I've tried searching but can't think how to word it to show up any results lol.

When I export my playlists and tracks to USB via Rekordbox export mode, I always get an error saying one or more tracks failed to export. The export log states that the failed track is a track that I know isn't in either my Rekordbox library or downloaded as a file on my PC anywhere. Everything else exports fine.

I know it's not really an error that affects anything technically, but it's a bit irritating having this show up every time that I want to export.

I'm on Rekordbox 6.5.3, Windows 10, and the export fails to any USB device I use (all formatted to FAT32), and am using an external SSD as my database. 

The export log only states this, which is the track I have removed from my Rekordbox library and removed as an mp3 on my PC:
