Charticulator Font not working

I used Charticulator to create a report, but recently, the version I used was deprecated. I recreated another visual using the new Charticulator Editor and Charticulator View, which is similar to the original visual. However, my issue is that I can no longer select any fonts—nothing happens when I click.

After struggling with this for a while, I went into the Power BI project folder and manually changed the font in the report.json file. Now, the correct font appears in the Charticulator Editor, but when I switch to Charticulator View, it doesn't retain the font from the editor.

I've tried uninstalling and reinstalling Charticulator several times, but nothing has worked. If you have any idea what's going on, please let me know

This is how it was initially and I wasn't able to change it no matter what I clicked.

After I when on and change the value from report.json and the editor is displaying the correct font.
