Check your assets for inconsitencies, I can see, even on one of the thumbnails, that the flag is not attached to the pole. Just because you use generative AI does not mean that your assets are free of errors. Quite the contrary is the case. You will have to correct all errors prior to submission.
Your titles are not very commercial. I understand that you are patriotic, but you will need to think more commercially, by using titles that will be used as search phrases. Nobody will search for "long live Indonesia", or a date (with some exceptions).
If yopu want to learn about the errors in the files, and you can't see them after checking your assets at 100%, post one or two here, and you will get one or more detailed analyses of the issues.

It is not a case that Adobe has outright refused your files. The reviewers found technical issues and wish for you to correct them if you can and resubmit the files. We can help you to find the issues if you post the files here at the original size you submitted them to Adobe.
