My external hard drive is showing with two names
It is causing problems as some of the files in the highlited folder is not showing in deluge.
I'm slightly confused... I haven't seen this behaviour before. 
This NTFS hard disk has two similar, yet different mountpoints that lead to the same files:
/media/s13rw81/8EE250E3E250D0D7/media/s13rw81/8EE250E3E250D0D71
I presume this was mounted automatically when you plugged it in?
Type mount to list currently mounted devices and their locations, this may help identify how it's mounted.
You can set up your own mount settings using gnome-disks (called Disks in Ubuntu MATE Welcome).
Alternately, you could unmount the disk and mount it again manually:
sudo umount /media/s13rw81/8EE250E3E250D0D7
sudo umount /media/s13rw81/8EE250E3E250D0D71
sudo mkdir /media/myharddisk
sudo mount /dev/sdXX /media/myharddisk
(Replace /dev/sdXX with the partition's identifier, eg. /dev/sdb1)
I tried doing that. It did not work. It seems this folder is being automatically created and consists of and exact copy of the other folder. I explicitly deleted the folder by selecting run as administrator and then moving it to trash but it came back as soon as i ran Deluge. I took the hard drive to windows and backed it up, them formatted it using Gparted. That damn folder remained intact. Could this be a virus or some sort ?
Highly unlikely to be a virus, possibly a configuration telling it to mount in this way. I am presuming you are unmounting the folder first before deleting it? (Best to permanently delete then move it to trash)
Try checking the /etc/fstab file in case there is an entry that is automatically doing this. If there is one for that drive, delete (or comment out) the affecting line.
Also, if it's just Deluge causing this, try resetting it by deleting its configuration files:
sudo rm -r /.config/deluge/
