Tried this. When I do that on the main body's group vertex tab it highlights the body correctly and selects the chest. However I noticed when I went to the shirt's vertex tab (which has all the same names) and go to edit mode the shirt is automatically fully highlighted for some reason. selecting or deselecting chest, etc. does nothing on the shirt

I've also tried it without applying the modifier, same result
