We have edrawings 2014 and 2015 installed. Can this cause potential problems or should I not be worried?
I don't see where having 2 versions installed should cause a problem by itself. There will be a potential problem caused by confusing them when opening files. Edrawings 2014 will not open SW2015 files.
I'm using 3 different version on same machine and use them as required. You just need to make sure that you don't open a lower version file in higher version and save that. This would overwrite the file and will no longer be able to open in lower version.
