I updated Flash CC and those sizes don't appear.

You can try editing the ipa. If you change .ipa to .zip, you can open it and search for your icon files, add the new ones in same folders, then update the application.xml with your new icons - youll see the current ones, copy them. Make a new zip, change it to ipa, and see if it works.

If not, get on the adobe forum, it has adobe people on it.
