Problem updating material with Blender tools send2ue 2.1.0

I am using Blender Tools - Send2UE v 2.1.0 to send assets to Unreal Engine v 5.0.2.

The first time I export, the mesh and material are sent perfectly to unreal.

Whe I make changes to the object in Blender and export again, mesh is updated correctly in UE but material is not updated at all.

¿Is it a bug or there is something I must configure in order for materials to be updated?
