Just DM’ed you log in info.
For the reusable element, I don’t understand why that would make a difference. I use reusable elements in almost every RepeatingGroup in my app and many of those have a working Fuzzy filter with it. Reusable elements mean that a Post will look the same no matter where it is viewed.
Since the reusable element is used to display a single result, why would a Fuzzy filter that searches for records be affected?
