Why does this if statement return false when the values are the same?

mentors = {"Enchanted4Dan","officialpm","AnuCat","Cald_fan","Alexoct"}
for i,v in ipairs(mentors) do 
    print(v..":  "..plr.Name) -- so i can see if the values are the same, which they are
    print(type(v)..":   "..type(plr.Name)) -- so i can see if the value types are the same, which they are
        if v:lower() == (plr.Name:lower()) then
        print("success")
                server.Remote.MakeGui(v,"MentorProgram",{
            StudentsCards = StudentsCards,
            MentorCards = MentorCards,
            Player = plr
        })
    else
        print(v.." and "..plr.Name.." are not equal") -- tells me they are not the same, when they are
        end
end

when it prints it prints this, this for my name

:: Kronos :: Cald_fan : Cald_fan

:: Kronos :: string: string

:: Kronos :: Cald_fan and Cald_fan are not equal

why doesnt the if statement return true?
