How to change the name of a custom licence plate in the parts selection menu

I've made a custom licence plate, but it only shows up in the part selection menu as "Licence Plate Mod". How do I change that? Thanks.

 

I believe you've followed this tutorial ? https://wiki.beamng.com/License_plate_tutorial

In the .jbeam file, you'll find this line : "name":"License Plate Mod",
Change it to "name":"yourLicensePlateNameHere",
