I can't move my profile back to my usual name

[BitOfFun]

Can you help? For some reason I have two sets of boxes with names in:

BitofFun>>BitOfFun

BitOfFunWithRudolph>>BitOfFunWithRudolph

I keep trying to alter the bottom one to put my profile back to my ordinary name, then press 'change', but it just says "Couldn't find a profile for you".

How do I fix it please?

Try it now, thumbwitch

All seems to be in working order again now, thanks Helen and NikitaTech! (Sorry it took so long, I had to kickstart my own hamster-driven laptop into responding )

Thank you Helen and NikitaTech!
