Hey,
One more thing came in mind after checking your xml screenshot.
Have you added ServProv id in CRT while uploading it back in OTM

?
Becase as a planner you may send CRT to many service providers so your CRT could be generic but while uploading it back as a servprov...you know what is the id of that servprov...
Try to add servperov id and then perform upload.
maybe getting in excel and adding servprov is easy option than adding in xml file...
