Presentation Page columns causing problems

I’m using the Mantra theme. I set up three columns on the Presentation page and used images 295x120px each. Then I added text. Everything looked just as it should. Then a day later, I looked at the Presentation page. The image in the third column was stretched to appear wider than the other two. The text had shifted and now is below all the columns.

I deleted the third image. Still the same. Then I inserted image 1 (that was appearing correctly) into the third column, to see if it would resize and things might fall into place. No such luck.

This same thing happened to me with the Parabola theme.

I have added a child theme and added 10px padding-right to #primary because I didn’t want the sidebar widget to align with the right side. That shouldn’t affect the Presentation page but I thought I should mention it. I currently have it turned off.
