OK, Phil, you got me. I thought all I did was copy the to address, but must have used a reply instead. Sorry.
Thanks for the code suggestions. I understand what you see as the issue. Makes sense. I will experiment with what you suggest and see what I get.

So, in your case the check items from both groups will be merged:

You could try changing the groupcheck query to something like:

Really the module should be recoded IMHO to do this:

usercheck = query("<radcheck query>")

if usercheck AND paircmp(usercheck, request):

userreply = query("<radreply query>")

pairxlatmove(request.reply, userreply)

if groupcheck and paircmp(groupcheck, request):

groupreply = query("<groupreply query> WHERE
GroupName=$group")

pairxlatmove(request.reply, groupreply)

...but I don't know if there's any interest in doing that.
