A320 certain buttons don’t work on overhead panel (help)

Is this more detailed, bug fixed or both ? I’ve just had a very frustrating time being ignored by the autopilot while some ATC numpty squawks “Please expedite your climb to 10,0000” … I’d love to, but it appears stuck and no combination of changing anything makes it work and it refuses to fly more than 190 on the level.

This may actually be me, but in the absence of anything resembling documentation it is impossible to know. My 40 years of coder senses suggest to me the Autopilot is buggy (being kind).
