Conflict with Advanced Custom Fields

I am using Jobs and Experts along with Ultimate branding. There is a conflict with J&E and Advanced Custom Fields by Elliot Condon

I have also tested it with Ultimate Branding, on or off it fails only when J&E is activated.

The fields are created even with the error. But they do not appear in J&E so I am thinking we cannot add custom fields. Any ideas?
