Well, since the duplicated profile from the default is for A330-900neo, The autobrake switch “sometimes” work sometimes doesn’t depending on the condition. I think the A330-900neo uses an legacy code for the old FBW systems. I remember I had similar issue the first time I got my TCA Addon where even the FBW A32NX didn’t register the autobrake switches. They end up fixing it on subsequent Dev versions. Which actually still works for me.
As for your issue, I would assume your FBW A32NX profile is still the old profile? You might need to do the same process of deleting the old profile, Back to the default, and duplicate that profile into the new FBW A32NX profile. Just make sure you don’t touch the landing gear or autobrake binding.
Just test using that. If the autobrake switch work, then it works. For me it works, I can set Max on the ground, and I can set Lo or Med while in the air using the same switch.
Once you confirm it works, just open the Sensitivity curve again for the newly duplicated FBW A32NX profile, and adjust the sensitivity to become linear (0% on everything except Reactivity which should be 100%). This should restore your detent configuration properly on the A32NX.
