Cant add iPhone video clip to Video-timeline, just audio-timeline

Hi, 

I have problems with adding a video clip from an iPhone to the timeline. I have sucessfully imported the video and can play it in the preview window without an issue. But as soon as I try to add it to the video-timeline, I cant, it looks like below image:

If I try to add it to the audio-timeline it works:

I cant figure out why this is happening.

here are the properties for the Videofile:

I have tried the following:

1. Clear Premiere Cache

2. Adding mp4 to the end of the file and imort it again

3. Used Adobe After Effects to convert the codec and container to see if that helpes. 

Im not sure what I might be missing and I cant find anything that can help me in this community or other places. Im quite new to this so it might be somthing easy to fix. Let me know if I have missed some crusial information or if you have any questions!

I hope someone out there is able to help me 🙂 
Thanks!
