Rekordbox 6.8.5 Export error with special characters and unable to drag and drop single song to USB playlist

Hello two issues:

1. I've experienced a bug when exporting to USB. I have a few Spanish tracks that have special characters (í, ó, ú, etc). When these characters are in the Artist or Album, they will export to USB, but will then show a "!" next to the name and will say "Error Loading. File cannot be found" in the USB playlist. I cannot load them to a deck from my USB onto a rekordbox deck, but they do play in Preview. To make these songs work, I have to delete them from the USB, change these characters to their english equivalent in my rekordbox library, restart rekordbox, and then import again. If I change the characters and export without restarting, I get the same error as when I exported them with the special characters. What is strange is that I already have songs on my USB where the Title has these special characters, and I do not experience this error with these tracks - they load and play just fine.

2. Now that you've implemented this mandatory Library Plus thing, I am unable to drag and drop a single track from my rekordbox library into a desired USB playlist. I instead have to put the one song on a new playlist, export the new playlist to USB, put the song into the desired playlist that's already in my USB, then delete the new playlist I just exported. This is absurd and messes with my workflow. Please make it work how it used to. You will likely suggest I use the Sync Manager to avoid this, but I've had nothing but horrible experiences with Sync Manager (missing songs, stopping during export, etc) so I drag and drop songs and playlists manually to my USB. I understand why it has this behavior due to having the two library types, but I really hope you can make the drag and drop work like it used to. 

Thank you
