Cannot "Add List" when creating Stremio addon

When trying to configure the Trakt addon on any browser at https://2ecbbd610840-trakt.baby-beamup.club/configure/, when pasting and/or typing manually the link to a list, hitting “add list” simply does nothing, and down the bottom it shows “No lists have been added yet” - i have also cleared all browser cache and cookies on all browsers tested on

This addon isn’t created by Trakt. Trakt staff will say contact the developer of this trakt addon.

Like the user above said. Please contact the developer of the third party app for problems related to it.
