TDB signal for one entire month

I started doing bug bounty this year and sent my first 6 reports on HackerOne. All of them were marked as informative or duplicate, except for one that paid me $500. That’s good and I’m happy with it, but that report is the only one open right now. I submitted it on May 6, so it’s more than a month old. None of the other reports should affect my reputation or signal, but I got put on TBD. I can’t submit any reports even if the program has a -1 signal requirement. I opened a support ticket that didn’t help me at all, and I even asked politely in a comment if there is any chance we could close the report because I have a TBD signal. I have two promising reports that I can’t even submit, and I don’t know what to do. Has this happened to anyone else?
