From the evidence you provided, it appears you only designed the form without completing the entire flow. Please review the screens I mentioned in the issue description and check the issue title (a multi-step form component with stepper). This issue will be merged anyway. Thank you for your contribution.

I did complete the entire flow, you could look through the file changed to see the project submittion flow was change the only reason the end point was going through was because I was getting a not authorized response whenever I make a call
