Gob Add on from Blender to Zbrush

I’m currently having a rather strange issue with the GOB add on. It’s my first time using it and it seems like I have no trouble exporting a file from Blender over to ZBrush, except that in Zbrush, it comes with a random mysterious cube.
Anybody have any idea why? I can’t seem to get rid of the cube in Zbrush either.

Here’s Suzanne with her mysterious cube.
