4K 60fps footage becomes 30fps when I export it

I've been using premiere pro for a while now and recently started with new 4K 60fps footage instead of 1080p 30 fps, today for whatever reason when I put my footage into my sequence it becomes 30fps, and even tho when pre-loaded it's 60 and says it's 60 when I got into the [modify clip/interpret footage/frame rate] but as soon as it's in the sequence or I go to export it shows up as 30 and says the source footage is 30 which it isn't.
