Ok, it appears the only way to fix this is going to a LIKE query. You can edit scripts/online.inc.php:
Line 89 has:
WHERE t1.ONLINE_USER_TYPE = 'r'
Change that, to this:
WHERE t1.ONLINE_USER_TYPE like '%r%'
Next, line 196 has:
WHERE ONLINE_USER_TYPE = 'a'
Change that, to this:
WHERE ONLINE_USER_TYPE like '%a%'
