[Koha] Help with Analtyics for the Manual

I'm working on the manual (obviously) and I need some help The analytics section says "To view all of the items tied to the host record, do a search for the record, click the Analytics tab on the left and the analytics tied to each barcode will be shown under the "Used in" column." but I don't see anything under the 'Used In' column on any of my records I do see 'Host records' with a link though. What should show in 'used in'? Thanks in advance!
