Delete an IP address removes half the IP address installed!!!!!!

I just tried to delete a single IP address that wasn't being used by any site. However after deletion half the IP addresses installed on the server that DO have sites attached to them have also been removed, and as a result all those sites are now down!!

WHY???

cPanel 11.25.0-R43471 - WHM 11.25.0 - X 3.9

 

Not sure why the forums has puit your reply before my first post??

I tried that and got this:

I did, however the warning message it gave me before hand said I was deleting a leader IP and that only 1 IP address (eth7) would be restarted. eth1, 2, 3, 4, 5 and 6 are on a completely different subnet.

 

Yeah the problem is now sorted thanks, however it just made me panic when half the sites stopped working and the IP list was shorter than expected.

Is there any reason why this happened? Is it a bug?
