No state set to SimilarityView and WaveformView when starting gui

I am using the sample data (https://github.com/kwikteam/phy-data) and am trying to see it in the phy template gui. Starting it with phy template-gui params.py --debug I see that no state is set to SimilarityView and WaveformView. In the gui, I see blank windows for both. How can I solve this? I get the same error using my own data output from Kilosort2.

Start from the phy template-gui params.py --debug entry point and compare the logged initialization of SimilarityView and WaveformView with the views that receive state. Reproduce the blank windows using the linked sample data and determine what state setup is missing; done means both views initialize with visible data.
