Strange issues with NAS drive

I have been using OSMC with a number of other plugins to populate my files. I had been used USB storage but I have just got myself a WD MyCloud and wanted to use this for my files to be placed in. So I have shared my 3 folders as below from the NAS. This is my fstab.

192.168.1.18:/nfs/TV /home/osmc/TV nfs nouser,atime,auto,rw,dev,exec,suid 0 0
192.168.1.18:/nfs/Movies /home/osmc/Movies nfs nouser,atime,auto,rw,dev,exec,suid 0 0
192.168.1.18:/nfs/Music /home/osmc/Music nfs nouser,atime,auto,rw,dev,exec,suid 0 0

They all shows correctly and I was able to touch files to them from within osmc. Great.

I have then ran some of my automated software for populating these folders which executes within osmc under various users. But since then my folders seem to be mounting weirdly:

drwxr-xr-x 2 osmc osmc 4096 May 2 2016 Movies
drwxrwxrwx+ 2 root root 4096 Nov 22 23:26 Music
drwxrwxrwx+ 23 root root 4096 Nov 24 21:48 TV

This seems to change as and when, I am unsure what is triggering the ownership on the link.

drwxrwxrwx+ 2 root root 4096 Nov 24 23:14 Movies
drwxrwxrwx+ 2 root root 4096 Nov 22 23:26 Music
drwxr-xr-x 2 root root 4096 Nov 24 23:24 TV

This second set is the same files shares after a reboot. This is creating issues with my software being able to write to each location. Even though root ownership on some shares I can still write from osmc user (root is on my NAS I think), but if osmc user then the mount is not usually created.
