That beacause the because the new serie the unicron trilogie (armarda, energon, cybertron) is a new story who have nothing to do whit beast wars/machine and the G1 universe. same thing for the serie Robot in disguise who is a independente story...
It was never stated that Cybertron was always mechanical. It's stated in the cartoon that it was a factory made by the Quintessons, but not that they made it from scratch.
It's fully possible (and perfectly in-character) for the Quintessons to have teraformed an organic world into a factory world. In fact in a time-travel episode where we see how Cybertron was under Quint rulership you see it had organic mountains, and in "Dweller in the Depths" we see an ancient area of Cybertron the Quints used as a lab for where they made all th early TFs, and it was an organic cavern deep within the planet.
And in "Desertion of the Dinobots" the Dinobots go deep within Cybertron to find an ancient Cybertronium mine, and when they do they see the whole place is lik an Earth mine, with dirt and rocks and stuff. No tech.
