Why is that?
Also what is .android secure?
The duplicated instances of recently added USB drives has been reported. It may or may not be the case that only one of them is functional. I'm not sure of the status of this but to learn more you could search the main thread for similar reports and mention there that it is occurring on your device.
IIRC, the .android secure folder is a native part of the OS having to do with secure apps on external SD but my memories of it are from back when we could move apps to external SD so you might want to do some quick research for a better explanation: "what is .android secure".
In KitKat some people deleted it (I used to but don't anymore). It may not appear in all file managers, and not all file managers are capable of deleting it, but I used to so with SD card inserted directly into card reader on computer.
