They moved it to "site set-up"
You have to click on each site name individually to set it up, it's at the bottom of the box.
Yh I found that option, but there doesn't seem to be a button to apply the new setting? It seems to register that I've set a preference on the table, but within minutes the change no longer appears on HEM (it defaults back to "none") and the stats change places on the table. Getting very frustrating :p
