Problem while submitting app


Hey Guys,

We have developed a web application using cloud API’s. While doing listing there is a section called To-Do list. We completed App details and OAUTH Integration setup except Android app. Because of my app is a web application I can’t generate and upload apk file. However uploading Android app is optional there. Now the issue is, I am unable to move forward i.e It’s not showing any option like NEXT or SUBMIT to proceed further. Can any one please let me know what I am missing OR where I am going wrong ?

Please check the below screenshot to know more about my listing.
