Entering K-1 for Invesco DB Oil Fund

I received a schedule K-1 (Form 1065) since I hold shares of the ETF: DBO (instead of a 1099-DIV which I was expecting).  I didn't know how to import it directly, so I entered the data using the guidelines in their instructions.

The issue is with Part III, item 11 on the K-1: Other income (loss) which has an entry for Code C, Sec 1256 contract and straddles with a value of -2,856.

It is triggering a missing entry error in my Pennsylvania Schedule D.  There are three $ columns:

Price less expenses, Cost or basis, and Gain or loss

For all the other rows in the PA schedule D, the price is what shares were sold for, the basis, and the difference being the gain or loss.

For this entry, the only thing entered in the K-1 was the Gain or loss, so it is displaying an error because there is nothing to fill the price column in the PA Schedule D.  It defaulted 2,856 for the cost and -2,856 for the gain or loss.

How should this be corrected?  Thanks
