Vehicles are glitched after replacing other vehicles?

I replaced the police riot truck with a bear cat and the mod works fine. After replacing the military jeep and a few other police cars the bear cat is glitched. It spawns in on 4 stars like it's supposed to but it just drives around without anybody in it. It doesnt chase you or anything it just drives around like a civilian and doesnt show up on the mini map as a cop. I did not mess with the bear cat mod at all, I only replaced other vehicles. I had to install a new vehicles.meta file for a different vehicle and I think that might have caused it. How would i fix this? Do i need to reinstall the vehicles.meta from the bear cat mod? Would that mess up the new vehicles that I installed? The barracks also does the same thing now, it also worked fine before. How would I install multiple vehicles.meta files at the same time? Do I need to mess with this file at all when replacing a vehicle? It said it was required.
