Have you ever run into a situation where your SemRush account doesn't display all of your sources in the source management? This might be happening since not all of your sources or projects in SemRush have set up Position Tracking.
To find more information on how to set up Position Tracking in your SemRush dashboard, please check here. After you do that, double-check if more sources appear in the source management.
If this didn't help with the issue, please reach out to our customer support team via live chat!
