Why are my comments repeatedly disappearing from posts yet they still show up in my profile? I really want to understand what's going on.

I thought maybe this was a one off thing, but it keeps happening and I have no idea why. This is the second account this has happened on now. If you go to my profile, you'll see I made 3 comments on a baking sub. Every comment (except for the first one for some reason) has disappeared after I made it. Can somebody please help me understand why this keeps happening? I'll never be able to establish karma is my posts keep mysteriously disappearing from public view.

Also, I've checked to see if my account was suspended, but it says I can't submit an appeal because "your account is currently neither suspended nor restricted." So, I'm at a loss. Please, somebody help me understand what to do or how to stop this from happening.
