Unfortunately, without a screenshot (which you could post here) or a dataset (which cannot be posted in the wiki) I'm not sure what the issue or solution could be.
I also would suggest posting questions like this to the Fusion discussion forum (http://forums.autodesk.com/t5/Inventor-Fusion-Technology/bd-p/370) or email labs.iv.fusion@autodesk.com. Those avenues are meant for Q&A like this. The intent of the WikiHelp is more documentation.
Thanks,
