Your next bet is to change the display order of the empty groups to 200 plus, or a number larger than the last legitimate group, then use phpMyAdmin to select the empty groups and delete them. Changing the display order makes it easier to do the query.
Assuming the display order for the empty groups are 200 and greater, this query will work.
There is a button that allows you to simulate the query. Verify the matched rows correspond to your empty groups. If it's a match, execute the query.
