Cine Camera parameters in Blueprint not updating or returning only default value

I’m wrapping my head around this problem. Some data from a Cine Camera Component aren’t updating in the blueprint and stay the same despite of how much I move them.

To troubleshoot the problem, I created a fresh blueprint, added a cine camera and built this setup so that I can monitor the Current Focal Length of the Cine Camera through a variable:

I then dropped the blueprint in the map, and changed the Current Focal Length of the Cine Camera:
Current Focal

But the variable is not updating:
Monitor Focal

What’s wrong with this?
