Error in accessing cookies to keep (whitelist)

I installed bleachbit-512-beta on my Windows 10 machine a couple of days back.

While trying to manage the whitelist of cookies to keep, I noticed some funny behaviour. Then I saw these lines in red pop up when I bring up the cookie manager.

===================
Failed to read cookie keep list C:\Users\user\AppData\Roaming\BleachBit\cookie_keep_list.json: [Errno 13] Permission denied: 'C:\\Users\\user\\AppData\\Roaming\\BleachBit\\cookie_keep_list.json'
Enumerating cookie hosts took 2.77s
===================

I checked out cookie_keep_list.json and much to my surprise I found that nobody has access to read the file. I am wondering why even the System is denied permission.
