I agree with @tagteam .
Each of the lines noted request detail on capital gains or losses which should be a net figure; and each respective line states "net".
The K-1 is prepared correctly as those figures will be reported separately for purposes of determining your taxable income.
The form 7203 is determining your net basis which has a different purpose.
