Delete source with remote SAPPHIRE ATI 5000023600

[Chiron]

You are right enabling this option allows me to delete files, but it's not what I want to do.
I want to remove some network shares from the screen, not the files on the shares.

I've created a test folder in an smb share.
I've added this source
If I delete it, it deletes the directory with the files on the smb machine, but not the icon. Obviously, if I click on it, it tells me that the share is not available.

Removing an upnp source is also impossible.
