IPA's Name Changed, Connect doesn't see the new Name

I have a published app. In the next version I added an action extension. This somehow changed the name of the IPA. Connect allows me to upload the IPA but does not recognize that it exists. I figured out how to force a change of name for the IPA before it is uploaded and now Connect sees it and starts "processing" it. But it disappears after a few minutes.

How can I fix this?
What is the right way of changing the IPA name?
