No button under the action section in domain wizard

Hey everyone, I'm new to WRF, and I have compiled the WRF EMS in my windows 7 laptop, through a virtual Ubuntu operating system. I have successfully run the benchmark case, and was planning to get started. However when trying to build my new domain, I couldn't see the update button or other buttons under the Action section of the domain wizard.
I have no clue as to what's the reason behind this. Any help would be really awesome.
Thanks in advance !!!
P.S. I have uploaded an image for your reference.
