A few verticies not responding to weight paint

I have a row of vert’s that do not change with 0% or 100% weight paint.
The green rows are attached to the same bone as the red center row. (lip-lower-def1.L)
While the green vert’s move with the bone, the red ones do not.
The red verts are associated to only the one bone.
What else can control these verts?
They do not move at all with the lip bones but do follow correctly with the head bone.

Please help.

Upload a .blend file would be your best bet.


Got it. Too many bones and i got a “.” I shouldn’t have had in the bone name.
Feel rather stupid now.
Must have tried to fix it for 2 hours.
