It's not hardware related because, I forgot to mention, once I managed to touch the ground (it was not easy) the throttle went in manual mode (it appeared on the PFD and I was able to move them again). Plus I spent five minutes trying troubleshooting while in air, so I recalibrated three times and afterwards went through all the checklist without success.

Hello, I already completed several flights without particular issues. Shortly ago I was on short final, I disengaged autopilot and autothrottle but there was no way to move the throttles. They stayed at idle position and the only way to move them was to engage autothrottle again. I wanted to go on manual mode but there was no way. Did I do anything wrong or it is a bug? Again, I already did several flights and never experienced this. Thanks.
