Only Uncategorized restrictions work

Facing an issue where by only the uncategorized page restrictions work.

I have 3 categories, 2 are open to the public and one is for members only.
The uncategroized category seems to be the only responsive checkbox within this addin.

It either restricts all content or none.

Any assistance would be greatly appreciated.
