Does not work with Divi Builder

Quite a good concept for a to-do list, but unfortunately the plugin completely destroys several Divi work areas in the backend, and some design settings in the frontend are no longer as they were originally defined. And this without any integration into the frontend via a shortcode. Very strange, especially the unwanted design changes in the frontend …

Any clue (as there is no similar plugin around), or did I miss something?
