1922 Church & Dwight Useful Birds of America Third Series (J7) Non-Sport Forum

There isn't a card size listed for this set. When I try to edit the set, card size is not an option. It is kind of important for this series because it comes in two sizes. The (J7) issue is 1 7/8" x 3" and the (J7a) issue is 1 1/2" x 2 1/4".

I'm assuming that the size cell gets locked for some reason. Is it an Adimin function to add the size at this point?

At this point Admin will have to change it.  This is why it is important to input correct card size when creating a set listing.

Sometimes you can access it by going to Things To Do, Set Validation System.
