SMB Problems - sees some folders but not others

I just got my RPI2, installed OSMC and went to add my TV/Movie folders. These are sat in a USB drive hub, connected to my server pc on the network.

When going to add files through the video option, it sees the computer and all the folders but won’t let me select any individual folder. It will let me select the computer as a whole and then sees the Movies in their folder but not the TV in their folder.

I’ve tried adding via the IP address and nothing either.

Does anyone have any ideas or a step by step guide on how to as this is driving me insane, it can see it but won’t let me select it!

I see posts like this probably every week and it always comes down one thing: Permisson settings on files and folders on your server.
