Turning off SG emblem shows a blank, white "chest detail piece" instead

[Zed]

Hello

 

With some costume combinations, when you turn off the SG emblem in the SG settings, it shows up a large white piece instead.
(Is that a giant sheriff shield insigna ? 😛)
Shown on this capture: Female model, Chest type Tights, Bodysuit Armored chest piece with decor, no chest detail piece.

 

It does not affect world render though, only the model in the preview.
