I am having the same exact problem with PA. Every year in the past, I imported all detail for federal and it carried over to the PA state forms correctly. This year it will not, it will only summarize. I got the same message about PA requiring me to send in all the detail. I understand that the federal return does not require all the detail, but PA does. As you said, PA should definitely be able to report the detail since we imported it all. I want to e-file as I've always done and hope that the sent copies of the detail will get matched up to my return correctly.
This is definitely an issue with the PA state software. I know you called support, but I am going to call also (as soon as I get done with the taxes, that is - I fear it's too late for a fix this year). Maybe if they hear from multiple people they will realize this is a real issue.
