DLC Components Boxes not stacking

Hi, I just got the mod and set perms. I can stack vanilla large wooden boxes. I try with the Components DLC boxes, and they do not stack. I can place one Components box, and stack vanilla large wooden boxes on it, but not allowed to change the skin with the spray can (attempting DCL box skins) I can spray standard vanilla box skins. Had a report of components boxes that were stacked by my previous mod being broken. The player isn't online so I cannot elaborate further on this. 
Was I mistaken to have thought that the components DLC boxes would stack? Or am I missing something in the config? 

The only change I made in config was default permissions:
 

    "default": {

      "Priority. (lower = higher priority)": 100,

      "Maximum number of stackable entities": 3,

      "Exclude stacking of these entities": [],

      "Maximum stack number per entity": {}
