You need to understand how an armature (bones) are connected to the object’s mesh data (vertices) using automatic weight.

• the shoulder vertices are related to these bones!

I must say, it can happen accidentally, sometimes easy to fix by modifying the weight map manually. Making it blue instead of another color. If the problem still occurs, remove all weight maps, Remove the armature connection to the object, and repeat the process.
Before that step, be sure to apply scale and check the mesh of your object.
