Liftgate oddities

2007 cx 9 grand touring
2011 CX 9 GT. Recently replaced brake booster, so battery was disconnected for a few hours. Next time wife used the vehicle, liftgate wouldn’t close when switch was engaged. Noted on subsequent use that when I engaged the switch twice in succession, it closed normally. Also noted that after being unattended for a short time, the liftgate closed automatically. This behavior was not present prior to having the battery disconnected for a while. Have Forscan and was curious if this was something I could reset/reconfigure in the appropriate module. Thanks in advance.
