I've seen this issue before, notably when numbers or symbols are used in the test report fields. We've notified Raz of this occasional problem in the past, but there has been no permanent resolution found.
I suggest that you type out your input ( at least) the fields that are descriptive and require more than a few words, in a Word doc. That way, if the report does not submit correctly, it will only be a quick copy and paste to recover it.
