Issue, Builded game send me wrong Surface Type

Hi,

I’m currently working on a personal project. I’m using Anim Notify to check ground Physical Material and send its name to Wwise to change sound (Photo 1). I have an issue when I’m getting the name of the Surface I’m walking on.

When I’m on editor everything is working fine (Photo 2)

When I build my game for debugging I’ve got these Physical Surfaces. (Photo 3)

Someone can help me with this issue ?
