Form not sending to receiver from

First thanks for an otherwise awesome plugin. Trust me I have wasted days of my life to find a form that can do what this does: ¨populating form field with url parameter (would have loved support for [shorcode] to use the custom fields, tho)

Anway

I use it so my visitors can contact the listing.. but I just discovered that the form doesn’t send to the primary receiver! Or at least it looks like it doesn’t. Have tried multiple email addresses ect. The other field seem to behave just fine..

When using tag to send to eg. {{nm_field_8}} I can see the same tag value in the preview. but the mail is not sent. when I add regular email to the ‘receivers’ field in addition, these go through no problem – but not the one that comes from the field tag ..

Try and modify url parameters in the link provided to test for yourself..
