Allow file deletion setting gone?

Hi.

Kodi 17.0-BETA6
LibreELEC 7.90.009

Guys – i cant find the “allow file renaming and deletion” settings in Kodi anymore.
I even tried changing the option allowfiledeletion in guisettings.xml to TRUE, but it defaults back to FALSE after reboot, and no Delete option in the context menu in the file lists.

Any ideas anyone?
