Unwanted HMD? (M2K5)

Hi all,
Since the new patch it seems my radar controls have changed:
I usually put my radar in ACM mode mid game and use the lock button to toggle it on/off, so I can quickly lock a target in front of me.
But since the new patch, the lock button does turn the radar off in ACM mode… only to turn it on in ACM HMD mode, which I do not want! (thus, it does not automatically pick up the target in front of me)

Is this a bug or an intentional change ?
I play the Mirage 2000-5F if that helps…

Thanks in advance ^^

Also, is there a way to move the in-game chat? It’s now display mid screen instead of bottom left, and overlaps with the RWR…
