Scrivener. Activation window: Mislabeled field: "license key" and not "serial number"

Scrivener Scrivener for Windows
1

When activating Scrivener: The field name on the Activation window is “License” but what is required there is the"Serial Number." The activation fails if you type in the License key in that field.
