Problem with subscriptions and Ping account

[xcinyue]

I ran into this problem:
When I go to https://ping.commishes.com/feed/ , my profile shows up with 0 subscribers, but when I go to it, there is also a subscribe button for my same account. I tried logout and login again, but it didn't help.
I also have one person in my subscriptions that I never even considered follow to, and their work in my feed makes me uncomfortable (no neg). I've tried unsubscribing, but if I go to their profile, there's a "follow" button hanging, and if I click it, an empty new account appears in the subscriptions. If I do the same thing with following accounts, I see more and more of them in my subscriptions. This problem hasn't disappeared for half a year and I can't solve it, because the bug doesn't disappear.
I tried to log in from another browser: opera, microsoft Edge, google chrome, but it turned out to be a waste of time, because even that didn't help. I use Opera GX myself.
I will provide a link to my page if needed.
