[Bug] All steps appear to have been completed when chooser is launched

[MuluhGodson]

Description

When using chooser, the user is required to proceed procedurally completing each step before moving to the next.
To indicate that a step has been completed, the number of the step is filled with green colour, else it retains its grey colour.
Presently when the chooser is started, all the steps appear to have been completed: ie, all the step numbers are green-filled.

Reproduction

1. npm install
2. npm run build-component
3. open demo.html
4. See error. [All steps appear to be completed]

Expectation

Each step number should only have a green fill when it has been completed.
