Solar File not loading

[empoweringhomies]

Just following the tutorial on youtube, i got up to the Input Data step on the Arrangement screen.
I selected 'Configure Data Sources' and it shows the options to select load and solar file. I select the demo files as per the video but unlike the video, the timeline of the two datasets are not generated. Subsequently, the 'Set and Autofill' function does nothing.

I have included a screenshot of the calculator.

I am using the Windows version
