New and lost - Switching from 3rd person to FP view

I did some research, and I managed to make blueprints so I can change camera mode from 3rd person to 1st person view - Problem I have is, that I can do this ONLY in Example map (before i load my project).
When I load my project, switching camera mode doesnt work any more. When I check blueprints, changes I made are still there.

Must be something simple I am missing.
If anyone can point me towards the right direction, I would appreciate it a lot!

did you put the 3rd/1st person switch in your level blueprint?
