FinSweet CMS Filter (Reset Button) Please Help!

Hello! I am working on a cms Filter system for a project of mine and I ran into an issue with the FinSweets “reset all” button. I watched the tutorial (2020) Create a Reset Button | How To - CMS Library for Webflow - YouTube - and I got it to work, but like in the comments of the video, i ran into an issue when selecting custom instead of default on the checkboxes. The reset button is a very important part of the project and I was wondering if anyone could help me solve this issue. Finsweet never answered the question everyone had they just referred to some help spot that I couldn’t figure out. Thank yall!
