Just to repeat recent advice on a similar problem:
One solution is to edit the leaprc file you are using (keeping a
backup copy of course), changing the AddPdbResMap part (this is the part
that tells LEaP to convert N- and C-terminal residues to their charged
counterparts).
The above is a bit of a guess: it allows control over which terminal
substitutions are made, and so may serve your needs.
