Decode Shifts

Hello together, I am unfortunately facing a problem. I had retrofitted the gearshifts a long time ago. Now I have dismantled them to sell them. Unfortunately, there seems to have been some changes in the coding during installation because I no longer have a gang indicator and a fault in the gearbox STG which says: Errors in gearshifts steering wheel. I already had contact with Zottel yesterday. He said I should look for it in Stg 46 and then delete the error. Unfortunately I find in 46 no fault and also no coding that I can change regarding the gearshifts. Does anyone have a tip for me? Is it a GP1 LG and thank you already.
