Engine Level Problem

Im using ; esx_advancedgarage, esx_lscustoms and esx_vehicleshop. But i have a problem. If i upgrade car’s engine to level 4 it works good. But after upgrade if someone drive this car, car engine is be stock. I looked for advancedgarage’s sql. In there engine is “modEngine”:3".
There would be 4 levels. And if i take car in the garage, again i can see it is stock engine. But in the sql it is not stock. How to fix this problem ? (Sorry for my bad english)

did you find solution?

I am not longer doing something about it. So i cant fix it.
