Basic copy from Mac Finder to Vox application of a folder does not work


If I copy a single file from Mac Finder to the Vox app in my iPhone management app in finder it works. Very often when I copy folders I get just a portion. See images below:ViewOfVoxAppInFinder FinderView
Note that there are only 1.04GB showing after the copy in the VOX app. There are 11.2 GB in the original folder.
