Error display on checkout items?

Hi, getting confuse on some operation:

1) By log in as a librarian /or volunteer to access “Library Circulation Desk”
2) Search the right patron
3) To view his checkout /renewal items.

Found that given checkout / renwal items have more than 1 page, the results from page 2 and on, are all reset as if listing all book circulation, not limited to selected patron’s records. Making me confuse if the “view checkout” / “view renewal” is for listing all patrons instead? And how about “lookup patrons”?

Hope to have your advice. Thx!
