failed to create file system

[maravento]

OS: Ubuntu 18.04.3 x64
App: rclonetray-1.0.0-x86_64.AppImage
rclone version: Included in appimage
Problem:

Workaround:
uncheck "Use the Rclone binary that is bundled with the app, otherwise installed system wide version will be used (if not found, then you will receive and error)"
and install rclone with:
curl https://rclone.org/install.sh | sudo bash
and create remote services with:
rclone config
and manage them with rclone tray, however it does not allow editing
