Playback for footage at 60fps lagging in Premiere Pro

Hello,

Today I seem to be having trouble playing footage that was taken at 60 fps (it plays in a "slow-motion", and lags behind the audio) within Premiere Pro.

-I first tried rendering the clip, then cutting the resolution down to 25%, with no effect.

-Then I tried bringing another clip, shot a 30 frames per second, and it played perfectly.

-After that, I looked under the sequence settings and started playing with the settings for editing mode, timebase, and display format. I believe that I will be able to solve the problem by finding the correct sequence settings for this clip, however I have not stumbled upon the right settings yet.

This is a new problem for me since upgrading to Adobe CC 2018.

Below I have pasted in the properties (as shown in Premiere) of the clip that is giving me trouble.

Type: MPEG Movie

File Size: 2.93 GB

Image Size: 1920 x 1080

Frame Rate: 14.99

Source Audio Format: 48000 Hz - 16 bit - Stereo

Project Audio Format: 48000 Hz - 32 bit floating point - Stereo

Total Duration: 00;18;51;12

Pixel Aspect Ratio: 1.0

You can see that Premiere thinks the frame rate is 15 fps.

On my e-drive the properties for the same clip are:

Type: QuickTime Movie

Size: 2.92 GB

Image size:

-Frame Width 1920

-Frame Height 1080

-Frame rate 59 f/s

Bit rate 1536 kbps

Audio sample rate 48 kHz

Any suggestions are welcome!

Thanks
