I have tried to add some existing attributes to the layered navigation filter options. I have set the attribute to be used in layered navi and set filterable (with results).
The Filter is displayed, but it doesn't 'stick' - unlike the other filters available and it does not limit the products in the category view.
I have tried re-indexing, deleting locks, re-indexing again and still the same behaviour.
I have checked the logs but nothing is being logged.
Has anyone had this issue before and knows how to fix any of the above? Any help would be greatly appreciated.
Running Magento CE 1.8.1 with the default navigation (no plug in)
