OK.  So 

My data is not corrupted.  This is not an issue with my data.  After 23 years using QB I cannot tell you how 100% positive I am about this.  

This problems happens with NEW invoices as well as old.  If I set terms to net 60, there is no problem.  ANY other terms setting shows as Past Due, even if it is credit card and the invoice date is today.  This problem started when I upgraded to 2020.     

Is there a way to turn off this feature?
