The Office US vs UK!

I have both versions of The Office, UK and US. The naming convention for each version are as follows:

The Office
|
| __ Season 1
|
|__ The Office.S01E01.Pilot.m4v

and


The Office (UK)
|
| __ Season 1
|
|__ The Office (UK).S01E01.Pilot.m4v

Both sets of TV shows show up under "The Office" US edition. When I click on a file, it give me the options "480p 5.1..." twice. One option is the UK version and the other is the US version.

How do I break out these two shows!
