Problem with adaptive headlights 5A4

Hi.

I have problem with my G20 330i 2020 with 5A4 headlights.
I bought BMW from USA, i had only left modules from headlight because old headlight been totally broken.

I bought 2 used headlights, used modules and mounted in.
I used E-SYS and coded both FLM modules for ECE typeschlusseln code.

At night when headlights are on when i moving steering wheel i have error "Adaptive lights malfunction" error code 805B79 - AHL Referencing rejected due to step loss" and both lens in both headlights are maximally to the left side.
I flashed both FLM modules to newest software but still the same.
I exchanged left headlight for next used headlight but still the same. The same error and headlights are on the left side.
