Automatically import client

Something is going wrong when automatically importing clients from other software.
I tested this with one client whom I sent a Gainz invitation to last month, but who let it expire (which I think is important). The client is created correctly with all available information, but according to the pop-up that appears, no invitation email was sent. Probably because that email was already sent last month; however, the client isn’t in my client list, so it should have sent an invitation.
The client in question is Hedwig Torfs
