I am unable to see any of the new updated items on my Windows 10 edition of Minecraft. I am not seeing them in my older worlds or in new worlds I purchase in Marketplace.  Not seeing any of the new ores or textures or mobs, like the glowsquid. Not seeing any of the new cave features.

In addition, when I do load a new world, I see a series of error messages:

feature registry errors, no definition found for feature.

also getting geometry error about the glowsquid
