Repeat value applied to normalmap shared with alphamap

Hi I am trying to apply different textures with different colors to different areas in my 3D model(OBJ).

I am doing this with a material list:

materialList = [
            //back
            new THREE.MeshPhongMaterial({
                color: 0x000000,
                shininess: 5,
                reflectivity: true,
                side: THREE.BackSide,
                normalMap: body_texture,
            }),
            //base
            new THREE.MeshPhongMaterial({
                color: 0x242323,
                shininess: 5,
                reflectivity: true,
                normalMap: body_texture,
            }),
            //sleeves
            new THREE.MeshPhongMaterial({
                color: 0x575757,
                shininess: 5,
                reflectivity: true,
                transparent: true,
                opacity: 1,
                normalMap: repeat_texture,
                alphaMap: texture_loader.load('texture url'),
            }),

And the assigning it to the object with the traverse function in the objLoader:

objLoader.load(
            'obj url',
            (object) => {
                object.traverse(child => {
                    if (child instanceof THREE.Mesh && child.name != "Cubo") {

                        let geometry = child.geometry;
                        geometry.clearGroups();
                        for (let i = 0; i < materialList.length; i++) {
                            geometry.addGroup(0, Infinity, i);
                        }
                        child.material = materialList;
                    }
                });
                scene.add(object);
            },

The problem comes when i try to use repeat on a texture to make it smaller. The alpha map on the same material shares the repeat property.

Can someone suggest me an alternative to reach my objetive?

Thank you in advance!
