Rekordbox / Dropbox Cloud Sync -Files not load after moving to online only

I have a professional subscription with cloud sync and I use all my files on Dropbox. Recently my dropbox local storage is up to 128GB and I want to free up space in my local HD. To do so I have tried to select a file and click (move to online storage only) as rekorbox itself have a display to do so in cases like this. But after doing it, I can't load this file no more, seems that the file simple disappear from my local or online storage. It does not show in my library with the "!" indicating missing file, it appears normal, with the cloud sign still pointing that the file is online storage, but I cant load it or even download it.
