Soooo...  I found this thread after I was having the same problem this year.  I reached out to ProSeries because it was not possible to ignore the OCD?!  Reconverting the files may have worked had I not already filed the actual returns.  We ended up with a work around that entailed making a copy of the file, checking the e-file acknowledgements on the copied file (which were now "accepted"), and deleting the original file.  Problem solved 🙂
