Sorting in facilities issues

The buttons to sort the list of available slaves when checking the Head Girl's Suite are broken

when any are clicked on this error appears:

Also, in the weekly report the player's choice of how the slaves are sorted in facilities is ignored. e.g., if you have slaves sorted alphabetically everywhere, that's how they're listed in the penthouse and facilities on the main screen, but in the weekly report slaves in the penthouse are listed alphabetically while slaves in the facilities are not.
