Today I modified some coin sheets. In one case the referee rejected one detail, because my modification request contained a changing relating to "type" (referee: "Tells me you updated 'commemorative' from 'No' to 'Unknown' as well"). At first, I thought, it was a mistake by accident, because I didn't changed this knowingly.
But in my second modification request was the same problem. I only added text and picture in "comments". But unter "change request" I see additionally: "Commemorative issue (en): Unknown".
I have noticed when modifying tokens the "Commemorating Event" box is fillable (as opposed to "Common Coin" it is not). I have been leaving the box blank, as none of the tokens I have recently modified have been commemorative. This causes the modification request to default as "Commemorating Event" "Unknown." The referee has been partially validating the modification, removing the "Unknown," as it is not a commemorative. So in the end the final entry is correct, but it seems to be a bug in the new template. This does not appear to occur with a new entry of a token.
