Scene trasfer from blender

The scene in the picture consists of 6 main meshes. (duplicated using alt+d)

I want to import this into Unreal the way it is but i I want it to import the main meshes it uses. I managed to do it by importing it as an fbx scene

but then the scale of the meshes are 100 and the imported meshes are tiny. How can i fix this?

thanks in advance.
ps: i don’t have the same problem when i import the meshes one by one
