Import Operating System Problem

Hello,

I'm trying to import a captured wim file in to "deployment workbench - operating systems" but It's not wotking

I've done this many times before with no problem but when I import this wim file it can't been seen within deployment workbench but you CAN see it in C drive. I've already trying refreshing and restarting MDT & the system MDT is hosted on but the problem still persists.

Here is a screenshot of my problem, as you can see the operating system cannot be found within deployment workbench but it is within C drive,

Thank you.
