You have selected Yes to the question Limit expenses to commission income? but the amount from the Commission income section is not going to T777:
Limit expenses to commission income? means Are you claiming employment expenses as a salaried employee or commission employee?
If the answer is No, then you are claiming employment expenses as salaried employee and should use amounts from the Salary section of T777 details.
If the answer is Yes then use the greater of the Commission or Salary sections, as its more beneficial.
In some cases, the Commission section amount will be greater. In other cases, the Salary section amount will be greater. ProFile puts the higher amount in T777, as per example in the CRA - T4044 Employment Expenses guide.
As an example, review the "Andrew" case from the CRA T777 guide:
