Nighthawk RAX45 USB Storage Share Name keeps on reverting to \\RAX45\USB_Storage

I have a two bay USB drive connected to my RAX45.

I use ReadySHARE->USB Storage (Basic Settings)->Edit to enter new share names. (See picture below)

Things work fine until I reboot the router.

After that, the \\RAX45\S_Drive gets changed to \\RAX45\USB_Storage. This has happened every time.

I would have expected the router to remember the name.

Is the name used here actually stored on the drive instead of the config data inside the router?

I see older complains similar to this on this site. But the suggested solution there is to reboot the router.
