I'm going to assume this code is in your script for entering the character's name during the game...

first try it like this

$ mcname = renpy.input("What is your name?", default="Daniel").strip() or "Daniel"

$ persistent.name = mcname

then in your code at the labels for the replay do this

label replayLabelHowOriginal:

            if _in_replay:

                show screen Replayexit #the optional exit provided with the gallery

                $ mcname = persistent.name #see what I did there...

that should fix your problem
