**Describe the bug in the current situation**
When the staff Login and click on Incorporate a New Benefit Company and when the staff clicks on the No Fee option then after the successful filing then the generated Receipt shows $350.00

Steps to reproduce the behavior:
1. Go to 'https://test.bcregistry.gov.bc.ca/'
2. log in as SBC Staff
3. Click on "My Staff Registry Dashboard"
4. Click on Incorporate A New BC Benefit Company
5. Complete the filing and click on No Fee option.
6. After the Filing is complete on the Dashboard open the receipt.
7. The Receipt shows $350 fee

Start at the test registry URL and reproduce the staff flow through the dashboard receipt after selecting the No Fee option. Compare the displayed receipt amount with the selected filing option; done means the receipt reflects the no-fee filing. The issue names no source files or tests, so the relevant entry point must be located first.
