To resolve this issue, open the app and navigate to the menu on the right side. Select the Settings icon.
In the Settings screen, look for a row labeled "Refresh Pick Data Download." Click on it to sync your local pick database, which should remove the graded picks. If the graded picks are still visible, try force-closing the app and reopening it to check if they've been cleared.
Please let us know if these picks have not yet been updated and we'd be happy to investigate further. You can reach out to our team here: https://btng.pro/help
