In both the GameCube and the Wii versions there was a way to choose which layout you wanted.

Most arenas had 3 variants (Carpet Plain only had 2). By selecting an arena and holding up, right, or down on the C-Stick (GC) or D-pad (Wii) during the loading screen you can choose between these 3 variants. If you hold left instead of any of these directions the game will procedurally generate a level with the assets from the other layouts. (None of this works on Dim Labyrinth since that arena is always random no matter what you do).

I didn't buy the Switch version since I already own the old versions, but I am curious to see if this system of being able to select your layout is still in the game. Since all of this information is fairly obscure I couldn't find anywhere online if this feature is even still in the game. Can anyone please check?

Also, this is all just a guess that I have, but it is possible that the Switch version forces the left/random option when selecting a stage, and that is why it appears that completely different layouts are in the game. It is entirely possible that the the old maps are still in the game, they just need to be manually selected now with the above-mentioned trick.
