Why aren't my collection page filters updating properly?

[RNA77]

Hi, 

All of a sudden our filters on collection pages, search, etc. are not working. The filters generate the filter-URL, but the page is not updating. Anyone who has an idea about what to do (using the standard Search Discovery App). 

Example here: 
https://rebelnomadapparel.com/collections/cardigans

If you try and filter, then nothing happens. 

Thanks in advance.

Managed to fix it. JS issue.
