Statistics keeps dropping a wifi interface

In Statistics / Setup / Network Plugins / Wireless, regardless of how many times I check BOTH wireless networks and then Save & Apply, the second one (w02) always shows up as unchecked the next time I visit this page. Only the first one (w01) stays checked between visits.

Wireless Network: Master "w01" (lan)
Wireless Network: Master "w02" (lan)

Thoughts?
