Images strangly importing out-of-order in Premiere Rush

Hi. I'm creating a slideshow style video in Rush comprising of jpeg photos formatted to 1920x1080 (72 dpi) in Windows PC for YouTube & I'm having a terrible time importing media in it's intended order.

All of my photos are identically formatted & tited suqentially in order by number - but for some reason I can't find a solution to - SOME photos are importing out of order in the program. For example, I will select (via import "Your Media") "Image_01" - but the software will import "Image_07" 

Rebooting, restarting the program - nothing works. All files are in their root folders on the desktop so nothing has moved - I'm very confused. Can't find a answer anywhere.

Please help!
