DHCP Scope turns blue with exclamation mark

I have two domains controllers. They both are having the same issue.

When I log into DHCP the icon is green and looks normal

When I expand the icon it turns blue with an exclamation mark

I looked at display statistics for all scopes and there is plenty  90% free on all scopes.

I know Microsoft says the below about the blue icon with exclamation mark......
DHCP server alert. No addresses are available from server scopes because the maximum (100 percent) of the addresses allocated for use are currently leased. This represents a failure of the DHCP server on the network because it is not able to lease or service clients

from here- > https://technet.microsoft.com/en-us/library/gg722802(v=ws.10).aspx     This is not my issue. I have plenty of addresses.

Any suggestions?

thanks

While your scopes may show as 90% free, are you taking address exclusions into account? Even a 90% full DHCP scope would make me consider deploying additional scopes or expanding the existing one.

I looked at each scope plenty of free addresses. I have two deactivated scopes would that turn the icon blue?

A disabled scope will change the icon to blue.
