Version ### 2.5.0.beta6 [293467a37a]
When I load the page
[https://example.com/c/slug/id/none](https://example.com/c/slug/id/none)
I get what I expect a page the includes only topics in the top level category.
if I then change “none” to “all”
I get what I expect a page with topics from all the top level category and all sub categories.
if I then change “all” back to “none”
It continue to get a page with topics from all the top level category and all sub categories.
if I then reload the page
I once again got a list of only the topics from the top level category.

This is a problem for us too, and I was just about to report it as a ‘bug’ as well.
I had thought that it was related to the recent addition of the Category setting that allows /none to be the default - but it actually just seems to be a bug as it happens in other categories too.

> Delighted to see that this has been implemented! Good work, @vinothkannans! When playing with it, I have the same issue noted here (can’t reply there as auto-closed) The url looks good, but the subcategory posts are still visible unless the page is refreshed. Please let us know when you have fixed it.
