Column sizes and font changes on own

Hi,
Mika & Branko provided me great assistance this morning with an issue. Now that I am back in and editing there is a glitch. The column widths become so thin the content is unreadable when enabling visual editor but only for 3 of the 4 columns. The first one is correct.

The font is normal in all 4 while in visual editor but columns 2,3,4 become BOLD when I update and close the editor.

First attached screenshot shows normal width but BOLD font out of edit mode.
Second attached show columns self-narrowed in visual edit mode.

Thank you
