vertex group with envelopes

Hi all:)
I’m new to Blender and trying to learn my way around…
I have a mesh that is the shirt of a character.
I want to animate it with an Armature.
I weight painted the center of the shirt to a spine bone
and for the sleeves I made few hand bones with envelopes
in the Armature modifier I checked bind to both Vertex Groups and Bone Envelopes.

The problem is when I have vertex groups assign to the mesh it seems to dismiss the envelope influence.
What do I need to do?
