Editing big shelf filter throws exception

[lilwhitemouse]

I have an error reproducible with only Deep Storage and Harmony in the mod list on a brand new game, after deleting my own config file. (To control for any outside variables)

If I try to edit what can be stored in a big shelf (or very big shelf), I get this error:

Because of course it does, because it's null, because it can already store everything
