AMBER: LEaP error : unbalanced charge

Dear amber users

I am studying the protonation state of heptapeptide binding with enzyme. In
this work, I also used RESP charge model to calculate deprotonate tyrosine.
But I found 1 error about total charge (-17.4815 ,do not add Na+ yet) when I
do LEaP. So, my question is "Can I balance this charge to zero ?", if
not, it means that this charge can be ignored right ? Or maybe someone can
help me solve this problem.

Thanks in advance,

Best regards,
