From the rulesheet:
Mansion: 3 Million: Awards 3 million, and on normal settings, spots the 6M mansion room if it has not yet been collected. For the purposes of end-of-ball bonus, the spotting of the 6M panel by this award is not considered to be an earned mansion room.
Mansion: 6 Million
Awards 6 million points. On normal difficulty settings, it also spots the 3M mansion room if it has not yet been awarded.
So it looks like normal behaviour to me. Maybe you recently changed one of te difficulty settings.
