Foam blocks in whisper quiet system.

Having AC freeze-up issues on new Bighorn, and poking around the ductwork I found a foam insert effectively blocking the front most AC exhaust vent. Seems wrong to me, and possibly related to my freeze-ups in the front AC. Anyone know about this?

More info...the front intake and exhaust vents were blocked, as well as the rear intake and exhaust. Heartland said shouldn't be that way, as did my mobile tech. I suspect just an error on the line putting the foam blocks before the end of line vents rather than after them...but effectively had blocked 20% of my vents. Anyone think this would contribute to freeze-ups?
