HELP! F21/F22 headlight conversion question

Hi all

Long time lurker, new poster... thank you in advance for reading this..

So, I bought an F21 M135i that had an F22 conversion done (poorly), main problem being very shoddy wiring work on the headlights, everything works apart from full beam - the lights will only 'flash' when I have the drl or sidelights on (pretty sure it's just flashing the dipped beam).

So - looking for the fix. My car came with LED lights out of the factory (15 reg LCI) and now has F22 Xenons fitted.

Any advice to help get the full beam working?

deleting LED lamp option and adding Xenon options to the VO if it's the case.
