It seems that the configuration was corrupted and the fix was to do a soft reset.
To perform a 'soft reset':
1. Go into "Settings" from the home screen, this is the cog at the top of the screen.
2. Go down and select "LibreELEC"
3. On the "System" tab on the left hand side, look for the option on the right hand side of "Reset System Settings to defaults" (at the bottom of the screen it will say in green SOFT RESET)
4. When prompted if you are sure, select "Yes".
You'll need the installation and setup guide to finish the configuration :(
