Schedule M-1 and M-2 are different

The total loss on Schedule M-1 and M-2 are not the same. Aren't they supposed to be the same. M-1 is correct and M-2 is incorrect. In fact it is off by the amount of the loan repayment made to partners. Can I just change M-2 manually? The system allows me to but I want to do it the correct way.
