A lookup for a multiple relation is going to return an array of multiple values. You can’t place a multiple value array into a single value component.

> You can’t fill a single value component value with a multiple value array. Plus, is that an array column or a relation column in your first screenshot? Relation columns contain entire rows of data. Not columns. You would need a lookup column attached to that relation, and even then the relation would need to be a single relation for you to use the lookup column in the component.
