Structure blocks on the other world in Minecraft?

I once wanted to create a server and made commands map etc. On a normal world. But now I have made myself a real server via Aternos and now I want to bring things from my world to this server. I saved everything with structure blocks and then wanted to load that onto the server. Thats not OK. Either I can't press "Load", or I press Load and nothing happens. Can someone help me? (Bedrock Edition)

You have to press save when saving to disk!

Thanks

Unfortunately, that doesn't help me, the problem won't be resolved

Am i doing something wrong?

You have to enter the name

Or you did not press save when saving

But I did both

I don't see a name when loading, because that's just an example

So enter ServerC

Yes i have. It says mystructure: ServerC
