Cant see some a folder on Storage

Hi,

I’m setting up a Raspberry Pi 3 with LibreELEC from scratch.

I have a load of backdrops which I’d like to use. I copy the folder ‘Backdrops’ using WinSCP into /Storage

But in Kodi, when I use File Manager to browse Storage, I can see folders such a Backup, Lost+Found, Music etc, but no Backdrops folder.

There are also a few more folders I can see in WinSCP, but are not shown in Kodi such as emulators and picons.

I guess its hidden some how? Is there some sort of setting I’m missing?

Thanks.
