Also note the instructions are still in draft form with IRS https://www.irs.gov/pub/irs-dft/i8995a--dft.pdf so that appears to be root cause.  That being said, you may still be able to file it, it's just that if instructions change, you may have to amend, but again, i'd refer to that critical diagnostic.  IRS instructions being in draft form, means until they finalize we can't finalize either.
