Scoutguard SG550 Pictures

I love my Scoutguard SG550 but there are a couple of times each day where it seems confused as to whether or not it should be shooting on infared mode or without infared.  These times are a bit after sunrise, and right around sunset.  What I have been ending up with are pictures that look like Negative exposures.  Here is an example below.  Anyone else seen this issue?  I was going to contact Scoutguard to see if they have any recommendations.
