World not uploading

I started a server, made a spawn in SP uploaded it, didn't work.

I don't know how to fix it not uploading the world. it was created in flatlands.

I made a spawn in SP and uploaded it to Aternos and when I got the server running, it didn't have the world I made.

The world type I created my spawn in was in flatlands.

Whenever I upload it again, it loads up a new normaI world instead of what I actually tried to upload.

Not yet, I will check it.

EDIT: I checked it, it wasn't the same,

SP coordinates -891.500 / 4.00000 / 109.500

My Server Coordinates 244.500 / 74.00000 / 212.500

Didn't work, it tp'ed me to a jungle biome,

I entered the coords again, still the same,

I uploaded the world properly, I did twice,

never found and errors in the logs,

I have uploaded it several times too, didn't work,

already tried re-uploading, I tried anyways, also didn't work,

I did try to look around for it, no luck... I still don't know why it isn't working.

Thanks for trying to help.
