Change Title Infos

Hey!

I´ve got a big Problem, I changed the title of several Songs in rekordbox, then i deleted the Songs on my sd Card and pulled the Songs again over to the sd Card ( with the new title), but rekordbox Shows always the old title. I think, the Songs were not really deleted!

The second Problem, when i Change the Rating of a song at the sd Card and klick right on the sd Card to sync with recordbox, this Rating won´t be synced to the rekordbox libary! :o

Please help!
