Catalog errors upgrading from 2.9 to 2.11

Our catalog of work isn't displaying correctly after upgrading to Contao 2.11.5 from Contao 2.9.

As an example, our catalog-reader won't properly show images (there should be one under the EMC Velocity Partner Kit headline). The images are also missing or misaligned in the related case studies sidebar.

Are there any edits I need to make to the catalog extension or code in order for it to display properly in 2.11.5? Thank you!
