What I found was that whatever I change the player's date of birth (in my example case, I changed it to Dodig's 2/1/1985) -- the age always stays fixated at 113, even when I (then) change it back to it's original date of birth (ie. Ancic's real DOB of 30/3/1984). Anyone else have this issue and/or has this been brought up before? Strange....

And yes, it's only this particular ATP player type --> (Edit: I THINK ANYWAY....if not, I will notify) .
If you revert back to the ATP ini file before modifications in the first place, the DOB is fine again.
Will post pics soon if more info is required.
