Nickel still scanning hidden Koreader folder

Hi all,

I have just installed Koreader, but Nickel still scans the hidden koreader folder and shows plenty of images in the home page.

I have added the required:
[FeatureSettings]
ExcludeSyncFolders=\\.(?!kobo|adobe).*?

in the .kobo/Kobo/Kobo eReader.conf file, before the first unplug after the koreader unzip. I can still see the line the in eReader.conf file (even if it is now moved of place within the file), so I definitely put it there!

I thought that the modification of the .kobo/Kobo/Kobo eReader.conf was all that was required to prevent the scanning.

I am using Kobo Libre.

Any ideas?
