Cessna Citation X Pulling up problem

[Samualon]

I've recently tried to do some flights with the Citation but when I wanted to land in an airport (after using the AP) and I needed to pull up the yoke to land I saw that it didn't work. Just like something blocked it to a certain angle (I guess 0 degrees). I put the nose down more and return but could pull up more than intitially. Because I can still pull up after pulling down first but not further than 0 degrees I think it has to do with something in the AP settings but I can't figure out where or what.

Thanks in advance for the answers!

Hi,
Did you disengage the autopilot? That sounds like it is still engaged.
