Realms deletes resourses.zip file in world folder when uploading

So I'm trying to upload a world to my realm with a resource pack in it(resources.zip) and when I upload my world to my realm, the resources.zip folder is not in the world save anymore, thus being no resource pack to download when entering the realm.

I've tried different packs as well, and none of them remain in the world file after being uploaded into realms.

I've been trying to get this to work for hours, but nothing has worked.
Am I just doing something wrong?
