That is true, but the change is not for all of my listings - only for 2 of them. However, the update page does not permit me to distinguish between my listings - so if i make a change to the listings that are now operated by my business, that will also change the information on my personal listing to look like my business listing, which would not be correct. The instructions on the update page say that the information cannot be changed once it is done, so if I change it to the business name, I wont be able to chnage the personal listing back to personal.
So I dont know how to do the update to that it works out correctly.
