Zipped datapacks folders get removed inside datapack when uploaded to realms

Creating a new world, and putting in a datapack (that has more than 3 namespaces) inside removes those folders before uploading to Realms. It seems that it always keeps the first, last and minecraft namespace (alphabetically) when it's on the Realms server.
