I'm using Oxygen Builder and Metabox Groups to house various PDFs, including an Image, a Title, a Blurb, and a text field for a PDF link. This is what the images within the Image Advanced fields look like when placed within a Group:

This is what they look like when placed outside of a group:

Here is the Custom Field structure utilizing the Group field for reference:

Any help on this matter would be greatly appreciated. Hope I've provided enough background.
