Hi @gisijam, things are looking much better 
one small thing, there is one extra A Record still remaining for the domain for IP 54.225.115.32. Go ahead and remove this IP, and then let me know and I am happy to check again.
Now, these changes to the dns might not be related to the issue with the menu dropdown, but it will help improve the speed of your site a lot I will also help to take a look at the menu issue once the dns is all setup
