TOPIC: Group Member details not appearing in Thanks Email

When setup in Configuration/Emails the group member details appear correctly for the resulting Administration Notification email. With exactly the same code in the Thanks Email, the group member details do not appear.
The email lines are

Group Members are :

{GROUP_MEMBER} [FIRSTNAME] , [POSTCODE] : {/GROUP_MEMBER}

The actual code is
<p>Group Members are :</p>
<p>{GROUP_MEMBER} [FIRSTNAME] , [POSTCODE] : {/GROUP_MEMBER}</p>

The Admin Notification Email shows
Group Members are:

mel amiss , 2109 : Rickardo Amiss , 2103 :

The Thanks Email shows

I have the same exact problem. Weird thing is, I noticed it appear suddenly, while configuring other parts of the plugin, rather than right after an upgrade or after modifying the email text. I could be mistaken about that though.

Guys... make sure you have the latest build of DT Register in place (2.7.1b as of this moment). If you do and this issue remains for you, submit a ticket. Thanks.
