Hi Niels,
Apologies for the inconvenience.
The issue you're facing is likely due to font settings applied directly within SP Page Builder. If you’ve selected a specific font (such as Roboto) inside a Heading or Text Addon, it will override the global typography settings set in the template styles.
To ensure your changes (like Preahvihear for H1 to H5) take effect across the site, please remove any font selections set individually within the SP Page Builder addons. Once those local font settings are cleared, the template’s typography settings should be applied correctly.
Best regards
