cannot customize world with the Terra 1 to 1 mod on server

On single player mode, terra 1 to 1 allows the user to make edits to the world generation. Otherwise, the default setting is of a random seed. The aternos server does not allow to make edits and the server properties is limited to the options tab.

Can you please help us with figuring out either how to change the default settings of the mod or change the server properties?

I tried the client generation of the world, the problem stands that terra 1:1 has a real time feed for a world generation. If i upload the world, i cant use the custom commands for the Terra Mod. Can you please help with that.

When i try to fix the problem by writing the world type, the server starts but no one can connect to it as the error of unknown host.

When I enter the world generation to be Planet earth, my spawnpoint was replaced and my custom command did not work saying this needs to be a terra 1 to 1 world.
