Georgiemoon’s 2018 charger gauge cluster issue

Hello all, idk if this is the right place to even post this but I’m having an issue with the immune layering (I guess?) on GM’s 2018 Charger pursuit pkg vehicle. Using the base strait into Zmod then bla bla etc modding yadda yadda. Then over in openIV in the vehicles.meta I’m copying the entire line from GM’s charger (18charger) right over to the new one same with the carvariation file, in game whatever vehicle I replace as “18charger” utilizing the provided vehicles.meta and carvariation.meta that works fine but if I add an additional one to the dlc (including that in the parent-child interior line) the gauge cluster is f*cked up idk what’s up
