Isotope glitchy

Im using Isotope and some custom code to do a search. The problem is ISOtope seems to be glitchy, especially when making filters that are very different to the previous one.

Check out the page here: https://sentinel-homes.webflow.io/test/iso

I have tried setting ISOtope animation to ‘none’ or ‘linear’ but not luck yet.

any help appreciated
