AppManifest.xml is being generated with the wrong version number

Question

I am having a interesting problem which is preventing me from submitting an update to my app to the Windows Phone Store. I have done this 100 times and something is wrong with visual studio building the .xap file. Steps I am taking:
Update all version references in project settings and appmanifestWM to 1.4.0.0
Build Release version
Copy .xap from /bin/release
Upload as an app update to windows phone dev site
What happens is that the current version of the app (1.3.1.0) is still listed as the version of the app that the submission page is parsing out of the version (1.4.0.0) .xap file. I unzipped the xap file and looked at the appmanifest files and found that
the AppManifest.xaml has the correct version number but the AppManifest.xml still has version 1.3.1.0. If anyone could help me resolve this issue it would be greatly appreciated.

Answer 1

Thanks for your reply. I believe it is a bug with my solution because I have now tried all of these steps on two computers and uploaded using two different browsers and I still get a AppManifest.xml file that has version 1.3.1.0. I will copy and paste the
unzipped code from the AppManifest.xml file.

As you can see the package version being generated is wrong. Can you explain where exactly in the solution that value is taken from? I thought it was from WMAppManifest but I could be wrong. 
Edit: In looking at the code above and then rereading what I wrote I realized my blaring error. I completely forgot that Silverlight 8.1 apps have an appxmanifest as well and that data is drawn from that as well as WMAppManifest. I never updated the version
in that appxmanifest. Thank you for the help and I apologize for my stupidity.
