300c 2010 5.7 mds

[LeonardoVega]

Good afternoon y'all.
I wanna know if I'm wrong or if this is how diablo works.

I"m trying to disable mds on my 300c 2010 5.7, and after I confirm the tune, I go back to the setting "*mds" and I see the "*" it's on the "on" instead of the "off".

Been trying to select lotta times the off, but it just does not work (in diablo i3 8345). I'm not sensitive to hear the mds working, so that's why I want to know if even when the asteric is on the "on" option, the mds off remains
