Apparently enough people complained that even though they added a light fixture ten times, none showed up, and the out-of-the-box Plan display configuration(s) were changed to have lights shown (in addition to the RCP display configurations, which is what had to be set current previously, to get light fixtures to display). If you want things back the "old" way, you will need to edit the display settings to have them not show in Plan display configurations. (No time to confirm now, but if memory serves, you will need to edit the AEC Content files and then edit the Multi-View Block definition(s) therein.)
I believe that you will need to anchor the lights to the grid as a separate operation after placing them. Too many things floating around in my head at the moment to remember if it was always like that or not.
