try going to the link again but don't change any filter values other than pressing the images (so that you can see all radio button appearing - there are 6). then play around and see that if you press, for example, the fourth image - what happens.
I have checked again in your website:
1) Deactivate custom JS Code "Search": hidden link
2) Edit the post view "tracks1" hidden link
in section "Search and Pagination", click "JS Editor", change the JS codes, add a line:
3) Test it in front-end: hidden link
Click the 3rd image, and check it in my Chrome browser, I see two results:
It should output only one result: 3, it conducts the problem.
Then I have checked the source HTML codes of above problem URL:
There are 12 HTML elements are using CSS class name "radio-trigger", as I understand from your JS codes, there should be only 6 HTML elements using this CSS class name, I suggest you remove the CSS class name from other those unused HTML elements.
