Alvin, That looks like an internal error message from some language feature you're using, unless you're using something like begin-lifted or syntax-local-lift-expression directly. Often the contract system generates names for internal use like "lifted.171", but there shouldn't be duplicate definitions, and if there are, it's likely not your fault. Can you share the code that causes this error message? If so, someone may be able to diagnose the error. Otherwise, with just the error message, we don't have much to go on.
