Images in Powerpack Flip Box All Justified Left Suddenly

One of the pages on my website has columns that contain Powerpack Flip Boxes. One day I noticed that all of the images inside these flip boxes suddenly have justified themselves to the left while the text underneath them has stayed in the center – I didn’t change any setting. I’m not sure how to fix this since adjusting the margins of the Flip Box moves both the photo and the text. I only need to move the photo and moving both of them together does not solve the issue of the photo and text not being aligned. I tried to just create them from scratch again but I face the same issue. Even when I create a new Powerpack Flip Box, the image is justified left, which it was not when we originally created this page.
