Your job is called  One_Way.tex  so will result in  One_Way.pdf .
When you  \includegraphics{one_way}  then LaTeX looks for an
appropriate graphic file to include.
The usual order of precedence is:
       one_way.pdf  >  one_way.png  >  one_way.jpg

Which one is found is now up to the file-system matching
provided by your operating system.
If  one_way.pdf   also matches   One_Way.pdf
then you are certainly going to have a problem.

I'm pretty sure that this will happen under Windows;
also it can happen on a Mac --- but I think there is a setting
to prevent it --- but not under Linux and other Unix flavours.
