Do Behemoth Portals scale down into... Lieutenants?

This is a fairly simple question/observation. For a while now, I've been running with bosses turned off while solo because I got fed up with the hassle. This causes bosses, when they span in my instances, to scale down into lieutenants with the same powers, but less hit points and offensive ability, essentially. However, I've noticed that not only bosses seem to scale down. In fact, I think certain "objects" might, as well.

Case in point - Behemoth Portals. Typically, these are fairly hard to kill, requiring some concentrated fire to bring down, but the payoff for them is AMAZING. I don't remember exactly how much, but I strongly suspect it's more than what I got now. I also remember them being tougher than the one I just fought.

Here's the deal - I'm currently playing a level 16 Claws/Regen Scrapper, and this is the first Behemoth Portal I've seen since I changed my difficulty settings on all characters. I'm very amazed with the Claws damage, believe me, but I don't believe it's amazing enough to have taken down a Behemoth Portal in around 5 hits. I destroyed the thing literally faster than the two Behemoths could run out of it. The reward it gave me was odd, as well. An even lieutenant gives me 171 experience points, while an even con portal gave me only 378, or around the experience of a boss, when I remember them being SIGNIFICANTLY more dangerous.

But that's not even the weirdest part. The weirdest part is that they don't actually have any graphics. You know the stone stairs and Stargate circle that has the swirling portal inside it? That's gone. It simply isn't there. All it has is the swirling vortex that disappears when you kill it, and that blue ring effect that's supposed to be inside the Stargate thing just hanging up in mid air. In fact, the blue swirling portal sort of drops down to floor level and out of the Stargate circle, I'm assuming because the stone stairs and platform that are usually at the base of each portal are gone.

Could Portals normally be bosses with extra rewards and be scaling down into lieutenants? Could it be that these lieutenants don't actually have any graphics for them, and so they only display their sprites? What the heck is going on here?

Not sure about the numbers, but I know for a fact that the portal graphics are very glitchy.

Case in point:
