Views not displaying all node reference items

I have created the view displayed in the attached image. The Day Packages field is a taxonomy term field which is set as the grouping field. The Package 1, Package 2, Package 3, etc. fields are package nodes, and the bullet lists are service nodes I'm referencing from the package nodes.

Package 2 references two service nodes which for some reason are not displayed. Package 2 should also display Manicure and Pedicure. Package 1 and Package 3 display these two services correctly but for some reason Package 2 simply won't show them. These two services are referenced correctly and visiting the Package 2 page shows them in the node reference field.
