Offline Files And Other R/W Access

I added offline files under a user's account some reason some of the offline files have access 'other R/W'. Some have 'user R/W', and some have both.Only those offline files that have access 'user R/W' and both 'user R/W' and 'other RW' work. When I try to make it Not offline available and then again offline available, it's still the same.So the user get's an 'access denied' or 'file location not found' error when he tries to open files that have 'other R/W'.
