Answer 1

You may have not add iMessage supported image (with size 1024x768) in your image asset. Add all missing images/icons in your app (related to iMessage, if you've added support iMessage)
See, for more details: Uploading app with iMessage stickers.

• Remove an emtpy Sticker Sequence in the assets, if you've any.
• Common suggestion: Use latest Application Loader to upload your app on app store
