Visio 2016 Shape Protection cannot be removed

I am using a Visio 2016 Cross-Functional Flowchart template - Vertical layout. I added two swimlane columns to the two columns in the prebuilt template, then resized them so that they evenly fit within the 11 X 8.5 in size. However, when I try to resize the Title column so that it is even across the page and does not overlap the right-most column, I end up either dragging the entire flow chart or I get the yellow "Shape protection,..." message in the 'Cross-Functional Flowchart - cannot edit column width' image. I tried the following things to be able to resize the Title column, but none work.

Also, is there a way to delete/remove this Title column altogether?

1. Ungroup - I get the yellow "Shape protection,..." message.
2. Edit width in Size & Position to 8 in. - width flips back to 6.25 in.
3. In Developer tab > Shape Design > Protection, remove all protection. I still cannot edit the width.
4. I went to the Home tab > Editing group > Layers > Layer Properties, and Lock is not checked.
