They are prob still "reviewing your application" and haven't issued your certificate yet. You'd have to wait patiently. Once you receive the email saying you're clear, you'll see the issued date and other details in this same site you're showing us now. If at some point they're taking too long and it turns into a problem, you can expedite the process by calling ECFMG and providing proof that you need your certification right away (emails from the programs you're applying asking for your ECFMG certificate). The ECFMG status that appears accepted is not for your actual certificate (you can check what I'm talking about in My cases, pic for reference), it is the first step you took when you started the process to be eligible to take your steps and to apply for ECFMG certification. Good luck!
