Whose credit you are pulling
Credit Bureau is where a pull is run and read. The selector at the top names the person everything below it belongs to, and it is how you switch to the co-applicant.
Why it matters
The two are pulled separately, so this control is the only thing telling you whose report you are reading.
Watch out
On a joint file, switch the selector and confirm the co-applicant's pull exists before you record anything.
