I'm receiving a critical diagnostic with the following message. Is the logic for the critical diagnostic incorrect?

An amount reported on Form 309, Part I is negative. Per Arizona electronic filing specifications, negative amounts are not allowed. This return must be filed as a conventional paper return.

Looking at AZ form 309, the number in part I is positive. There is a statement #1 reference that contains two line items that are feeding into 309.

Statement #1 
Line Item #1 - is Positive

Line Item #2 - is Negative

The result is a positive net amount that is showing on Form 309

Is this truly a problem with efiling (the negative line item on the statement) or does is the statement irrelevant for efilling and as long as 309 has a positive net number?
