Hi, i found strange behavior of the navigation by clicking on the (none) category. Here is the way to reproduce it 1. Follow to [Extras - Discourse Meta](https://meta.discourse.org/c/extensibility) 2. click on (none) category 3. click again on (none) category You will see that pages on 2. and 3. steps are different. 1. step * * * ![](https://global.discourse-cdn.com/meta/original/3X/a/1/a1b473a6e32c0695c2c933d0aed79ea249e7233c.png) 1. step * * * ![](https://global.discourse-cdn.com/meta/original/3X/f/1/f14e67b31e7b01024c1e7534df4f5b7784fa84b0.png) ---

There is already a bug on this, the only difference is the topic excerpt for the pinned topic does not display, yes? Other bugs on this, same thing. ---

Sorry not sure that i understood you correctly. 1. I thought that (none) category should display topics which assigned only to first level categories (extensibility). But on the step 3. displaying (all) topics which assigned to (plugin) os (sso) 2. Anyway double visiting same page should lead to same results, isn’t it? ---

Oh my bad, you are correct. I should have looked closer. ---

I was about to report the very same issue (the excellent search function brought me here). The bug is still present in latest Discourse (2.0.0beta10). ---

So what I see here is that the second click on none is basically doing a “all” instead of a “none”. Will see if I can fix this. ---

This should be fixed by: [https://github.com/discourse/discourse/commit/a8079ab6793c72de06b5dd82c1feeaebf9b0b37f](https://github.com/discourse/discourse/commit/a8079ab6793c72de06b5dd82c1feeaebf9b0b37f) While it’s not exactly fixing the issue, it will not show “none” anymore if you already are on none, preventing this issue from happening. ---
