No custom characters appearing

[neon-the-dev]

Hello, sorry if this has been issued before but I can't seem to get custom characters working in the Wheel Wizard for Retro Rewind..

(Characters skins are on)

(Birdo is supposed to be Kasane Teto)

(Mods are enabled)

I dunno if it's my own stupidity or not, and if it is I'm sorry, but I'm just desperate to get this working.
