Web Interfaces Running Through Portal - Tab Spacing

When a web interface is created in BPS_WB and run through BPS_WIF0, tabs and spacing are correct. When the web interface runs through the portal, the spacing on the tabs is off. Tab 1 is perfect, Tab 2 has one blank line /space before the functions / layouts, Tab 3 has 3 blank lines. How do I resolve this? Is it a template issue on the portal versus BPS_WIF0? I have tried playing with the spacing to no avail.

Thanks
