Glitch with detective clues, makes arresting the right suspect impossible

All of my clues pointed out to one sim (female, elder, wearing skirt and tank top, gloomy, grey hear - eeeverything matched) and when I tried to arrest her I failed. Then I tried arresting a random sim (which was adult female wearing dress, with brown hair, was not gloomy) and I got it right.
Why do we even bother looking for "evidence" or collecting"the clues" in a notebook if it will be 90% wrong?
I read that some clues were supposed to be wrong, but in this amount - it's just ridiculous.
