I am sure I am missing something simple here, but.....

How do I add unopened material to my collection here? I have seen it listed on the right hand column when updating collection on some sets, but not all. For example, if I am in COLLECTION, BASEBALL, SETS, 1982 TOPPS, ADD UPDATE....on the RH column it shows "

Unopened Material

You have 0 unopened items listed.

Howewer, if I am in 

2020 Panini Contenders Draft Picks - Legacy

there is no such entry method listed in RH column.

You have to make sure you have a collection selected in Collection Summary.  Once you do, an "Add Items" link appears.

Thank you.
