When trying to assign IP reservation in IPAM, Domain does not appear in Forward lookup zone drop-down list

Question

I am trying to assign reserved IP Addresses through IPAM that is installed on a Server 2012 OS.  Here is the procedure I have been following:
Login to IPAM server
Open Server Manager
In left-hand column select IPAM
In left-center column expand IP ADDRESS SPACE
Select IP Address Range Groups
Right-click the appropriate address range and select Find and Allocate Available IP Address
In new window, scroll down to Basic Configurations
I can input the basic configurations with no problem.  DHCP Reservation Synchronizations look good too.  But when I get down to DNS Record Synchronization, I can't do anything with the Forward lookup zones because nothing appears in the drop-down
lists and I cannot manually enter the zone name.  Here is a screen shot of what I see at this point:
Without completing this information, I cannot complete the Address Reservation.
Any help or insight will be greatly appreciated.
Thanks!

Hi Tom,
This happens if your DNS servers that are managed by IPAM are not authoritative and primary for any zones, if they are not authoritative for the appropriate zones, or if there are not any DNS servers managed by IPAM.
See the examples below. Here my DNS server is authoritative for 4 forward zones and 2 reverse zones. I can choose any of the forward zones but assuming I pick a range such as 10.0.1.0, I would be unable to choose the 168.192.in-addr.arpa zone because the
IP addresses do not match.
