Why a translucent influence dont work well in the lightmap build

Good Morning, I had some issues when I need to build a lightmap, the translucency color influence dont work well. Like the images, I had a red translucent volume, a single Directional Light and Sky Light, ambient is 0, if I change the color of the translucent volume change the wall color, it happen always when I build. Someone know what are happening here?[1]
