Camera won't change after compile

So, my problem is that I update camera position in my blueprint class and click compile, everything is okay and then when I go to test my new camera position it is the same as before, no change at all.

Does anybody know what to do or try?
Best regards.

Picture is below

my assumption is that you need to save blueprint after compilation and before exiting. But please give a screenshot of your problem.

do you have any more suggestions? I have problems now with my both cameras. Follow camera (head) and Aim camera on rifle.
