No..Please don't send any query regarding address missing. It is a regular process of your file. So if your address is missing it means VO is reviewing your file and you should get some news after reappearance of address in 10 -15 days. So if you will ask them, they will give you common answer that your file is under precess.
Note: In any of your query to CHC, you should be very polite. You should not blame them that why my address is missing or why I am at the same stage. Instead you can ask politely that when can i expect my next stage..etc etc with thanks.
regards,
