Email sent to wrong person

Hi,
First of all thanks for this plugin, and I’m glad to see that its development is not dead ??
So I just come to report that when changing the status of a feature request, the email telling the user that the feature has changed status is sent to the admin and not the creator of the feature. This may be related to my configuration where it is not possible to register on my wordpress but user can still post features request with their email.
Anyway,I’m the only one receiving the email, which is not really usefull ??
