Let me see how best I can assist you with this one. To ensure that this issue is not being cause by a plugin conflict I would recommend that you temporarily disable all your non-toolset plugins and check the button again and see if it starts working again.
If not could you copy and paste the shortcode in you view filter output so I take a look at it.
I was not able to see an issue with the code. Also testing the reset button on a sample site I have works as intended.
Would it be possible to recreate the view ? or a secondary view for testing ? This will help to identify if there is something wrong with the view itself or if the problem is something deeper.
I did check with the default WordPress theme and it works. Indeed, the bug is not on your side : I contacted the support for the theme I use, because the free version works fine, the pro version doesn't (like I said earlier, bugs with the parametric search). Apparently, something to do with the jQuery update since WordPress 4.5
Thanks a lot anyway for your support !
