It is not applied the scale object that parented with armature (weight painted).
Exact steps for others to reproduce the error
Add a Cube and a single Bone.

Scale up them at the same time.
Apply scale.
Armature is applied scale.
But object(Cube) is not applied scale
and object becomes the size before scales up.
