Received alert for breach which is not in the dashboard

I received a legitimate email from Mozilla Monitor stating my data had been found in a breach of Paidwork. I've signed into the dashboard but there is no trace of the breach there under action needed or fixed, and nothing on the notification bell. Not sure what to do next, I want to know whether my data was actually exposed and what to do about it. It makes me worry what else has been breached that I'm not being notified about, because if it can fail this way then why not the other way around too?
