Hi,
The distribution itself is correct – as you can double check for example by assigning any Custom Object – or changing the Template used (to for example a Simple 3D Tree). For some reason (might be, you’ve moved accidentally its Pivot Point), the One Plane Template object, isn’t correctly aligned – to fix it, you can delete all content from the forest_templates layer, which will be recreated automatically.
Hope that helps.
Best regards,
