Bricks / Metabox Clonable groups

I have a CPT named Skills. Now I’ve added custom fields through Metabox, these custom fields are in a group that is also Cloneable. However, when I clone and save the values of this second group, how am I able to use its content in Bricks? By default a query only returns the values of the first group, but not the second.

I have also made a relationship between the character and skill.

How can I achieve this?
