Hi 

Can someone please help me?? I´ve created a manual payment called "MB WAY" just for testing and now i want to create the real one "MB Way" however shopify dont accept this one because i´ve already created the other one so, how can i delete the manual payment (not deactivate) or change the name ?

Thanks

Please help me beacause my store is almost finished and i really need to launche it as soon as possibile
