DOTM Cyberverse playsets question

I've just opened up my first DOTM Cyberverse playset, the
Bumblebee Mobile Battle Bunker. It really is an amazing little set,
and the wings/jetpack for bumblebee is a very impressive add-on
to a legends class figure.

I'm having trouble though with the instructions, and converting to
APC mode (this is the truck-trailer mode, with the missle launcher
concealed, bumblebee on the back, and his jetpack stowed on the
front of the truck). It doesn't show clearly how the jetpack attaches,
and as far as I can tell there aren't any pegs to clip it into (though
I can see holes for pegs on the roof of the truck - and on
many other parts of the truck so I guess there must be later
add-ons that integrate).

Can anyone who's opened theirs tell me how to attach? Both
the jetpack and bumblebee just keep sliding off when the
truck is in motion.

There is no place for it to attach, I've tried a few times to no avail. The only place it attaches is A) bumblebee and B) the underside of the ramp.
The top of the truck has no slots or tabs for the jet to attach.
It could be a pre production photo like ROTF Starscreams flip out blasters

Well that's a relief its not just silly me!
Sometimes I have trouble following 2D representations of 3D diagrams, and I couldn't work out what I was missing.
Bit of bluetack should do the trick!
