Bolding PropertyManagerPageLabels

Ok, this one may just be a bug but bolding a PropertyManagerPageLabel causes bizarre effects with its styling. By bizarre I mean it creates the white background and it changes the font size. The attached picture demonstrates my point. Does anyone know whats going on, or how to simply bold text without all the bizarre effects?

My code for creating and bolding the label.

controlType = (int)swPropertyManagerPageControlType_e.swControlType_Label;

caption = "Parent Link";

alignment = (int)swPropertyManagerPageControlLeftAlign_e.swControlAlign_LeftEdge;

options = (int)swAddControlOptions_e.swControlOptions_Visible + (int)swAddControlOptions_e.swControlOptions_Enabled;

pm_Label_ParentLinkLabel = (PropertyManagerPageLabel)pm_Group.AddControl(Label_LinkName_ID, (short)controlType, caption, (short)alignment, (int)options, "");

pm_Label_ParentLinkLabel.set_Bold(0, 1000, true);
