Dual slash marks in file path

So I cannot figure out why when I open my assembly I will see a dual slash on my file paths. I see this in the file reference occasionally as well.

Anyone ever seen this? Unfortunately we are not on any PDM sort of system at this time. We are working towards it, but its not something that will be here soon. Currently we are sharing the data over 2 external HDD's... its absolutely insane and extremely cumbersome. My frustration in this method is driving me crazy, but its all they will purchase for us right now... stupid, 110% stupid.... arghh!
