To-do App created using React, SCSS, Beautiful d-n-d

Hello everyone, Just completed this project to the beat of my ability using react. I decided to use react as I though this project would be easy, it is not as I thought. The project is a very good challenge.

I learnt a lot about filtering in react and JS, about state, components, sass and react in general. I would recommend new react developers like myself try this project.

The only issue I can not resolve is when you click the active filter, and then click the all filter any tasks that have been completed, the checkbox will be blank but i have checked the state use react dev tools and its says it is true. I don't know what to do. Cheers.
