Trying to add a category product filter, but does not seem to be working / can't get it to work as I would expect.
What (I think) should happen:
Set up the category filter. Settings -> Product Filter -> Add a new filter -> and I've added a filter named 'Category' using 'Category' as the filter type.
When someone clicks on to a main category page, the filter appears, allowing the user to see/choose the sub-categories associated with that main category.
Instead, what is happening:
On the main category page, there is no filter showing at all.
On the sub-category page, the filter appears, but only showing the parent category as a filter option! No other categories?!
(Kind of like the reverse of what I would expect to happen).
Am I missing something? Doing something wrong with the setup?
Any insight or help greatly appreciated.
