V11 - Order of Nodes displayed in Network Map

Hi all.

Something seems to have happened to my network map since upgrading to v11, not sure if it related or not, but wanted to get advice on how to remedy it.

The nodes used to be listed in a logical order, but now appear in a different order. Is there any way to control how they list in the network map? A change to the bigip.conf perhaps?

Thanks in advance.
