FiveM ELS Lights Syncing

I am having trouble with ELS lighting in my public server.

Currently we are using this system → Union Mods - British ELS | Emergency ELS

However, all the lights and sirens are syncing with each other (different players in different vehicles sync the sirens).

For exmaple: if I were to turn on my lights and sirens, another player across the map would have the same effect and their sirens + lights turn on as well. This is server sided, so players around them hear their sirens / see their lights turn on as well.

Does anyone else have this issue? We have OneSync enabled on the server.

Would be grateful if anyone knows a fix for this or reason why this is happening!

Thanks.

snap did you ever get a fix
