AoE IV Survey: Bug about the "Updates List"?

Hi, i’m trying to answer the Survey but, at the question:
"For the following list of possible updates, changes, or content additions, please rank them from what you would most like to see to what you would least like to see. **

Drag items from the left-hand list into the right-hand list to order them."
There is nothing to do. And i can’t finish the Survey…
Did i miss something?
