As well you should be ticked at this point!  I wasn't able to receive help in a timely matter with this either.  I ended up mailing my forms late and I used the old -misc forms.  Now I have to file amended 1099-NEC to correct everything and they will end up handwritten.  

With the alignment issue, I copied multiple forms to use as 'dummy test sheets'.  I made adjustments to the alignment until it was 'acceptable' then used an actual form.  Hope this helps in the future.  Good luck.  And if you ever get the NEC print error figured out, please share.
