[Uploading Nether and End not working]

nevermind! once i set my world to the default, it just worked?

[Uploading Nether and End not working]

YES! I HAVE BEEN HAVING THE SAME EXACT PROBLEM

 

I'm trying to upload a skyblock map to the server, but it only uploads the overworld and I have no idea how to get the nether and possibly end in! WHY IS NOBODY ELSE HAVING THIS PROBLEM????
