[Koha] OpacHiddenItems being ignored?

[Richard Hills - TechnologyWise]

Hi,

I am hoping someone can help me with this setting as so far no matter 
what I set here I am unable to exclude results from the front end search 
system.

I have set the value of OpacHiddenItems as follows:
restricted: [1]

However restricted items are still coming through in results.

I have also tried the value "restricted: [1,2,3]" incase it was an issue 
with a single item being passed through.

My Koha version is: 3.4.02

Thank you.
