Why can't I import my Chrome personality?

I’m on Chrome on MacOS. I want to import my main personality that has all the info I need. When I do import, it just shows me all the other persons, which I rarely use. Why would some persons be available others not? Is there some way to work around this, like to export my personality from Chrome, or to “unlock” it? Sorry, I cannot give you a way to reproduce this. I just googled this, and found… zilch. Hope someone can help, or I doubt I’ll really start all over and switch to a new browser any time soon that doesn’t know all the stuff Chrome knows for me.
