Is there any way to clear those "warnings"

I don't know why Bukkit keeps printing this warning. (those are not errors, "just" warnings)
It does look like when you join you are very far away from the world origin (0, 0), so it might just be that.

Once a chunk loads, WU gets that chunk and looks for saved blocks. Therefore, it must access the chunks, even if it prints those warnings.

This could be because of a custom block (like the Elite Crafting Table or Advanced Crafting Table from CustomCrafting).
However, that should only happen when that chunk is loaded. Unloaded chunks are being ignored.

Is there any reason why that chunk might be loaded? Maybe a player is that far out and placed that workstation?

I don't know about this but I turned off the Advanced workstation and still got the error
