We apologize for the inconvenience you’ve experienced.

If you are attempting to upload multiple font styles at once using a single webfont file, this will not work as expected. The system only supports adding one font style per upload. That is why only a single style has been applied, even though your font package contains multiple styles.

To use all 14 styles, you will need to upload each font style individually. At the moment, uploading multiple styles in a single step is not supported.

We appreciate your patience and understanding. If you need guidance on separating or uploading the font files correctly, feel free to let us know.

Best regards

There's a little extension that fixes that. ;)

Since yesterday, it works not only for Helix Ultimate, but also for Helix3 — including variable fonts.

Changes to fonts apply globally via the template settings, not via SPPB. However, SPPB integration is planned for a future release.
