Apparently downgrading to 15.0 fixes this issue.
As stated in another comment, and on the documentation the version string did the trick for me, going directly with numbers should fix the problem E.g. 1.7.9
Version Number(required)
The version number of the app you’re adding. This is the version number that will display on the App Store for customers. Numbering should follow typical software versioning conventions (for example, 1.0 , 1.0.1 , 1.1 ).
When you create a new app or platform the version number will always default to 1.0, but this can be changed before you submit the app for review.
Important: Make sure this App Store version number matches the version number set in the bundle. If these don’t match, upload errors for later updates might occur.
