any guitar players or musicians?

I’ve put up some pictures, so hopefully that will explain some more. It’s a classical guitar with vinyl strings. My first response would say it does not hold tune. That’s why I tried to tune it. But now, I’m not so sure anymore. When the string popped out, I did put it back in and gave the pin a good firm push with a twist. It still popped out. And to answer Jim, yes, I do mean the B string. There is no metal loop right up under the pin. There is a metal loop at the end of the 5th string that I replaced.
