Composite roles can't be filtered out of suim search

Dear all,

There's been an ognoing issue with the massive search using suim. My intention is to search for which roles each user has. The issue is when I filter out Composite roles.

Here's a screen of what a suim looks with the filtering of Composite roles:

The roles marked in red seem to be Single roles, but when getting into the user's profile these are not among the Single roles:

This bug happens when doing this check with multiple users. When checking the user all by itself this bug doesn't occur:

I hope there is a work around this issue, if anyone has encountered it before.

Thanks in advance.
