Pershing NetXInvestor 1099 Import

I am having trouble importing my 1099.  I was able to import it last week but there was information missing.  Specifically it wanted me to categorize 87 stock transactions as long/short, covered/noncovered.  I deleted the import hoping that there would soon be a fix.  Now when it try to import my 1099 it says that nothing is available to import.  I clearly see my 2020 1099 on the NetXInvestor site.
