The new features from the Minecraft 1.17 caves and cliffs update are really great. However I've observed that some of the new items like Copper, amethyst, and the spyglass in addition to other new items are missing from certain Minecraft Marketplace maps and mashup worlds. I have screenshots to show some examples comparing worlds that are unaffected versus worlds that are missing 1.17 items. I noted that the new 1.17 update features can be found on normal Minecraft worlds or worlds where only the textures are changed.

The problem is found on Marketplace and Mashup worlds. I went into creative and survival mode and I couldn't find certain items such as the Spyglass and Copper. I tried making new worlds, redownloading, and even reinstalling Minecraft but nothing seems to fix this bug. All of the Marketplace maps and Mashup packs that I purchased seem to have all the features up to the nether update.

I really enjoy the Marketplace and Mashup worlds that I've got, and it would be nice to know that the items and features from the 1.17 update are working on all of the Minecraft marketplace and mashup worlds.

Thank you for your time.
