How about CVs, devices and benefits?
And on vacation limit page I see always the inactive user.

1. As an admin, when I go to page with equipment I see error:

2. On CV page, inactive users should be marked somehow - like gray background or so

3. The same thing on page benefits-reports/1

4. ON users page, inactive users have red background but on other pages gray. Can we unify it somehow?

On benefits report page still we don't have marked inactive users (at least I don't have)

And I still have problem with equipment
