To update your Mod, click : Admin -> Files -> Add a new file .
To check your Mod is correctly loaded, add this line, under [Player0042] :
Name = Anton's Carlos Alcaraz
(and then delete it and re-update the Mod

)
Maybe it'll get listed in Settings -> Profile as well, but I'm not sure.
I checked your Mod and you put "-1" & "-1.01" ; it shouldn't have these as "-1" means the player won't play that year. ie: remove all the "-".
