Unable to cube Loveless Persona

I got a Loveless persona a week few and today I've decided to cube it with regular miracle cube. But when I tried to cube the cane it said This item's potential can't be reset. Does this mean you can't cube the Loveless weapons?

Thanks

Edit: Nvm guys, i forgot to use the advance potential scroll I bought. Yep cubing it now, 9%Luk so far. Thanks
