Form 7302: Line 3A cannot have a gain in Part 1 and a loss in Part 3

Hello - I am trying to E-File with TT. I've been trying to get over this one hurdle for about 2 hours with no luck. I've watched a tutorial on the form an am confident it is correct. I have no loses to report so Part 3 is all zeros. So not sure why I cannot get rid of this error.  My K-1 is very simple and this is very frustrating.
