Unable to upload files from FTP

VLC[v3.2.0(334) on iPhone 6(iOS v12.4.1)] unable to upload media files from FTP. To reproduce:

Upload on FTP two media files(or .VLC-playlists).
Open FTP folder with this files in VLC and press cone icon to upload media file-№1, but file will not be downloaded. I'm noticed that if right after that I press cone icon to upload media file-№2, media file-№1(but not file-№2) will be successfully downloaded. Please fix.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
