Hey Venkatareddy,
it looks like the “Icon menu items” part of the “Icon menu” settings tab has been lost along the way. There are two ways we can proceed in this situation: you can try removing the live website and migrating it again, so that the glitch is removed, or you can give me access to the WP back-end and the ftp (sending the relevant information to support@satoristudio.net secure box), and I will try to add the missing field. The second path may take some time (1-2 days), as it depends on how much data has been lost during the transition to the live server.
Sincerely,
Andrii / Satori Studio
