Project income report - "changes to balance forward"

SOLVED

In Project Income report, there is "changes to balance forward" line for some Projects  - please see the picture below. Job # 19TM011: Robson Park - does not have the line, but Job # 19TM012" Broadway and Cambie" does have the line for "changes to balance forward".

How can I post entries to show "changes to balance forward"? 

The reason I'm asking is that I discovered some transactions were incorrectly allocated to the incorrect job ; thus, the balance forward is not correct.

I cannot adjust the incorrect transactions as they were previous years - I would like to correct the previous balances, so when we run the project report, it will show the correct REVENUE minus EXPENSE amount (profit).

Please help me & let me know how I can adjust,

Thank you !!
