Bone keyframes for datarefs

[Im-Unknown-now]

I'm having an issue in which adding key frames for bones on the Bone properties panel doesn't work while on object properties works fine, I don't get any error when it happens so I'm not sure what may be the issue, maybe it's the blender version. I'm using the most recent update of Xplane2Blender(v4.3.3) with blender 4.3.

How can I fix this?
