You know it was explained on the wiki that the omnitrix symbol's correct and properly functioning placement is on the chest for ease of access.

It was retconned that in the original series the symbol went all over the place because the omnitrix wasn't calibrated for ben properly at that point, unlike alien force and Ultimate alien

so as long as that hasn't been rendered non canon among with pretty much everything else then it means the new omnitrix isn't functioning properly either.

That being said I like Humungasaur's chest belt ^^ to bad he can't grow in size anymore.
