HA 84.6 with Group has Topic switch the issues error in log

I just created a test group in Home Assistant 84.6 that has all 7 entries for a panel(testing).  Noticed that there was a eight entry showing but not configured, a switch for the group name.  When I engaged the switch I go an error in the log file:

'Service binary_sensor.turn_off not found'

What might this switch be and how might I configure it correctly as it looks like a useful switch to have
