First thing to do with HCML/HCMR is reset them with OrBit, ECU Tools tab, change the Active ECU dropdown and click the "Reset" button. It may not help but good to do, will force the HCMs to load the latest configuration, as well as there is nothing like a reboot to fix random issues. There is no calibration for headlamp level or aim, it is physically adjusted with the aiming adjusters, that is all there is as far as I know. Check codes after the reset of the HCMs, see if any have been set which might then give a clue to what the problem is.
The config in the CEM will never brick anything in another module. There are config items, the software in each module reads the broadcast config, it either accepts the values for the config items that it uses, or it does not accept them, in which case it will set a code for "invalid configuration".
No worries on the L/R detection, that is how the HCM module detects whether it is connected to a L or R headlamp hardware, one side puts voltage to a detection pin, and the other side lamp does not. You would expect them to be opposite.
