What is one of the reason that the category of personality disorder is controversial?

There is many reasons why personality disorders can be controversial like the following
• Personality disorders can be mistakenly diagnosed. Like most other disorders as well, it's not that uncommon to happen.
• It can make you feel labeled
• Sometimes when a patient doesn't fit into specifically one category, they may be diagnosed with more than one disorder.
• One thing I've personally noticed is that a person under 18 sometimes may not be diagnosed with a personality disorder yet but it's diagnosed with something different than what they should actually be treated for. I've found that personally annoying because, sometimes it's clear they have a personality disorder or they match for it. But sometimes it just depends, Y'know. It depends on who is evaluating you.
