Bug in Schedule E worksheet?

There seems to be a bug in the software. I separately posted that I sold two rentals and only one shows up on form 8582. 

 

During the interview I indicated that both were sold. From some experimenting, I discovered that if I indicate the property that's missing from form 8582 was not sold (uncheck the checkbox during the interview or directly on the schedule E worksheet for that property) then it does show on form 8582. 

 

How do you report suspected bugs?
