If it's not working correctly, then you must ensure first that the seed is correct, and secondly that you're using the correct seed version and Aristois version.
Aristois doesn't currently have an option to switch the version, so if you were to find the "seed" of a server on an incorrect version, or use Aristois on a version different than the world was created in, the ore positions will be different.
Here is a screenshot using 1.18.2, with a world created in 1.18.2
