Rotation Constraints not working

Hello everyone, can I have an opinion with this, I’ve been trying for a lot of time to find a solution to this but I don’t get it.
I am trying to rotate an actor in only one axis and lock the other axis but constraints don’t lock it.
Here is a video with it’s behaviour:

This maybe is really easy but I’m just struggling for so much time and don’t find a solution for this.
I also tried with Physics Constraint Component with no luck :frowning:
Thank you,
Adrian
