Cylinder Reflection

Hello, I’m new here and I don’t know if this is right category but anyway.
So, I’am newbie in cinema 4D and trying to learn by watching videos etc, I wanted to ask u if you know why when i put a cylinder object it’s not the same in symmetry and has not the same reflection and when i’m trying to move the normal it’s just changing both locations and they must connected!
Sorry for my english :frowning: thanks for help.
