I have a content type that uses the Moneyscripts File CCK field type and I have it set to "Unlimited" in the Global Settings portion of the CCK field editor.
It operates fine when I select from the File Plans drop down, and displays all the selected items, but when I "Edit" the node they are associated with, the select dropdowns are all empty and I need to re-select them, or they get removed from the node.


Also happens when not set to "Unlimited" (ie. when using it as described in the support docs.)
