Its impossible to analyze, reproduce or let alone fix your problem with the small amount of information that you provide. What is your code? Is there a sample file? Which operating system do you use? Please try to provide a reproducible standalone test-case which shows the problem, otherwise there is likely not much we can do here.
We cannot reproduce the problem with the scarce information that was provided, so we cannot do much here unless we get more information. Thus closing this as LATER for now, please reopen with more information if this is still a problem for you.
