Tried comparing it and it was identical to mine. Try viewing the Page Source and search for elements "fromScratch" and "fromWebApp" just to verify if those was rendered properly in your app.
I have figured out something on this. Its the URL.
As I have disabled the pacific header I am getting the below dialog when click on 'New Application' Button.
When I choose 'A New Mobile Application' and press 'Create' button it open the page with "......./master/setup/pacificMobileEdit.jsp?appId=-1" URL where it says 'pacificMobileEdit.jsp' is the page opened. Hope this would be a bug to be fixed or do you think I have to adjust my setting to correct this one?
When I replace the 'pacificMobileEdit.jsp' with pacificMobileCreate.jsp in the address bar it loads the page with Create Option available.
Tracking via PSC00320391. Indeed the URL should be pacificMobileCreate.jsp.
In the meanwhile may I suggest editing common.js at tomcat\webapps\master\js location in both master and prod wars to get going...
Look for the line with "else if(appType=="MOBILE")" and replace
Sorry for the trouble.
