Custom Emergency Sirens won't change for Vehicles that aren't Police ones.

Hello, I am a pretty experienced user when it comes to LSPDFR and Modding it but i have encountered a Problem which i have never heard of and I can't find any solution for.
I've recently completely re-installed my LSPDFR and like always I changed my ingame Emergency Sirens and installed ELS.
However if i drive an emergency vehicle like an Ambulance or anything that isn't a Police Car which has an ELS.xml in the Folder the Sirens which are set for the Police Cars start making sound instead of the actual ones that are supposed to. 
It 100% has someting to do with ELS since i already reinstalled the game twice since that Error and it only occurs with an xml in the ELS Folder.
Now I've done a little testing but all my attempts failed. Different Sirens don't work (Always same Problem), same with other Vehicles + ELS files. I also tried messing with the ELS.ini and installing the older (1.00) version of it. 
At this time i don't know what could be the solution since it allways worked in the past an I couldnt find someone else who has the same Problem than me.

I am open to any suggestions and would be happy if this issue gets resolved.

Thanks in advance
