Premiere Pro not loading full media

 Hi all! Premiere Pro isn't loading my full media. Regardless of how long the original file is, it only uploads 4.28 seconds. This one in particular should have been 7 seconds long. I have other files that are like 30 minutes that are only uploaded as 4.28. Any help would be much appreciated! I have version 14.2.0, a Macbook Pro (2018) and filmed on my iPhone Pro 11. I'm retrieving the video straight from the Photos app.
