Limited Partnership Losses T5013

I just filed a return and the NOA came back with good news for the client. The client had a substantial amount of unused limited partnership losses, which I have not dealt with before, and CRA applied their taxes owing. There was a return of capital this year which reduced the value of at risk amount, but nothing showed up in Box 109 on the T5013.

Did I miss something and what should I have looked for? Is this something TaxCycle should have picked up on? What should I look for in previous years to see if I can find more savings for the client?

Thank you folks and as alway your knowledge and insight is appreciated.
