'Source Sans 3' Uses Incorrect Family Name

When downloading the typeface 'Source Sans 3', the resulting font files list the Font Family Name as 'Source Sans 3 ExtraLight' instead of just 'Source Sans 3' . You can view this is something like FontDrop.info.

So then a resulting bold font may be titled 'Source Sans 3 ExtraLight - Bold', for example. Seems to be the case for any of the weights or styles.
