Premiere's Import Image Sequence not working like After Effects

I have a folder of hundreds of GoPro Pictures (shot as a timelapse). I go to File -> import, then i highlight the first picture I want to import, but before I press the import button, I press the "show options" button on the bottom left hand corner. It presents me with a checkbox that says "image sequence" so I check that box. Then I select the first picture in the folder, because if I attempt to highlight all the pictures in the folder, then the "image sequence" checkbox grays out. So with the box checked, I highlight the first picture in the folder and press import. And all it does is bring in one still image. thats not an image sequence at all.....  If I go to the SECOND PICTURE in the folder and highlight it, (repeat the same import process), it imports a video file that is 1 second and 4 frames long (and its noticeably missing a ton of photos from that big folder of GoPro pictures). Anyone else have this issue with Image Sequence not working?  (If I go into After Effects and do the import image sequence process, it beautifully creates a 32 second video file from all my gopro timelapse pictures. Which tells me that premiere is importing my files incorrectly, with ommitance)
