screen "Newsletter : Add Users to Lists": no colors

joomlamailer version:1.7.2
Joomla! version:1.7.4
PHP version:5.3.6
MySQL version:5.1.57


In the screen "Newsletter : Add Users to Lists", if I select my "test newsletter" from the drop down, user coloring works (I get green for users that are subscribed to that list).
If I select my full newsletter (38k members) then I get no coloring, even though I know for a fact some users are registered to it.

Can you help me with this ?

Also (I think I made that request earlier, not sure if it was resolved):
On that same screen, can you create a way to filter users based on the coloring (show only un-subscribed, etc...). I have a lot of users on each end (Joomla and Mailchimp), and using a checkbox to deal with all un-subscribed users manually is not applicable in my case.
