[Plugin: Flexi Pages Widget] Changing the width of the selection vbar in Flexi Pages

Using the widget on the main page instead of sidebar and having huge issue. I believe the width of the bar itself is interfering with the sidebar. How do I shorten the width to a precise width? They all need to be shortened to the same width. Check front page at https://sportsmediamasters.com to see the issue. Thank you.
