Cannot Get 60FPS To Play at Normal Speed

I recently shot a lot of footage using a Panasonic GH5 at 1080P and 60FPS but I cannot get it to play at normal speed within Premier Pro CC 2017. I am trying to mix it with footage shot at 29.97FPS so first I imported the 29.97FPS footage and let Premier Pro create a new timeline for me with sequence settings of 29.97FPS to match the first imported clip, then I added the 60FPS footage to the timeline.

Everything I read says the footage should playback at normal speed but it does not. It plays back at half speed, also in the media bin it still shows the original duration of the clip, I would think it should show a clip half the length of the original clip if the speed was doubled. If I go in and manually set the Speed/Duration to 200% then the clip looks normal but I should not have to do this and I think it will be choppy when I render to output.

Any help would be greatly appreciated. This is my first time working with 60FPS footage and I just cannot figure out why it is only playing in slow motion. I also tried a 60FPS timeline/sequence but it did the same thing.
