MixItUp Filter is not working anymore.. why?

Hi

Hi

I am currently working on a filter system for a website. I am using the MixItUp Library. According to the following guide I proceeded for it:
http://mixitup-webflow-tutorial.webflow.io/dynamix

When I first used test data, the filter worked cleanly. But now, it simply no longer works. So the filter just doesn’t work. I don’t know what the reason could be and so I would like to ask you. What am I missing here? Here is the link to the project:

Thanks in advance for any tips.

Best regards

Hi @kealga. welcome to the forum :webflow_heart:

Where is the element with the classname .filter-category ?
I see it in the mix-it-up code, but not in your cms elements. Did I miss it?
