[RAS] Claimed items and "role" in RAS

I just checked my list of claimed items in the author service. There it says "Here are the 42 items that you have accepted so far. You can tell us what role you had in that item." In the table there is also a heading "your role" but the corresponding table cell is empty for all items. What is the purpose of this? I find it a bit confusing. /Sune
