Isotope filter broke - help

I set up @SidneyOttelohe’s Isotope filter and it worked perfectly for a couple of weeks. Now it’s acting weird (see below). I’m not sure what changed. I haven’t touched the code.

Current behaviour
When entering the page only one item shows up.
Clicking on any of the filters will start showing items, but the animation (which was super smooth before), is now glitchy.
From second click on it is acting normal again.

Any advice on how to debug this?

Thanks!
