losing setting of images slide in

When you open and save restuarant module the images loses it settings for some reason. The image thats on the rightside ends up on top and the images on the leftside ends up on the bottom. How can I fix this problem?

Here's a copy of the screen

Hi

Please disable using editor while editing this module. Tinymce is stripping HTML5 code which is required there. You may also try with a different editor.
