[HELP] When I add vehicles with lights, sometimes it breaks other light colors/patterns

Hello all! Sometimes after I add a car with a certain light pattern/colors, those lights may work properly, but they break other lights like shown below.

These lights used to be in a basic red/blue rotator pattern, but now all the colors are on one side and have a steady-burn pattern like some of our highway cars that have been in-game for months.

We recently added a coroner van and a firetruck that we suspect may have broken these lights. Is there any way to prevent this? This is a common problem we face, and we suspect that it is caused by conflicting files, but the files are all in separate folders, etc.
