Files failing to upload

I've been struggling to get some files to upload to the MuseScore server. Attached is an example. The desktop client says upload succeeded, but when I click on "Go to your score" I get the message "Score is being processed. It will automatically be displayed when finished". If I use the web client to upload it goes directly to that message. I've left it for long periods of time on that screen and it never seems to resolve. I've had this problem with several files. Some of them upload successfully after several tries, the attached has never uploaded successfully. I have a complex process, I am posting lined out parts for a choir. Due to the vagaries of history I convert pdfs to xml, use Finale for main editing, and am now starting to take those files from Finale via xml to MuseScore. So pdf->Photoscore->xml->finale->xml->MuseScore. It seems possible that I'm picking up some shrapnel along the way that is causing the problem. Attached please find a post-Finale xml file and the related MuseScore .mscz file.

Thanks in advance!
