In clips on edit video jumps back to start of clip while audio seems fine - proxies?

I'm fairly new to Premiere as far as using mor than basic editing. 

I started having these issues only recently when I started trying to use 4K video from my iPhone 11 in my videos. 

My PC is nto a dedicated editing rig but it is not slouch. Nonetheless, when editing these large files it is nearly impossible. So I learned to use proxies. 

Somehow it seemed like it worked perfectly at first. I had automatic Ingest presets and after setting it up initially it was just working for several videos. Then problems started. 

The best I can explain it is describing what happens in one clip in particular. 

It has a proxy file and looks sync'd when I switch back and forth from proxy to original. 

But what I see on export is at the point where I cut 15 seconds from the clip...the video jumps back to the start of the clip while the auidio continues to play as normal. 

This is not reflected in the timeline preview. Only when I export it. 

I tried deleting the media cache and export the clip again but it did the same thing. 

I haven't tried recreating the whole project or segment since deleting the cache but if anyone thought it would not be a waste of time I would. 
This is one of those things I suspect might be common but not common enough that I'm able to find an article to fix it. 
Or I'm not searching the right way. 
Anyway...thanks.

Correct answer mwhain

SOLVED: The answer was that this was happening on files from my iPhone. 
The best solution for me was to change the format my iPhone recorded in to Compatable. 

A workaround that lets you keep using their prefered format involved using VLC to convert the files into MP4 format. This worked fine but added extra steps and time but if your files are already recorded in that format this is an option.

NOTE: I tried to convert the file (they MOV files) using AME to YouTube 1080p based on a potential solution I found on this forum but the converted files are doing the same thing even BEFORE I edit or export them. 
I converted them and they come out as MP4's. I put it in the timeline and just looking at it...

At 43 seconds the video jumps back to the first frame but audo continues on...

Then about 40 seconds later it does it again...

Then about 35 seconds later again...

Then 30 seconds later...

Then it does it randomly between about the 45 seconds to 30 seconds
Like groundhogs day! 
Again...I can hear the audio running and it's not looping...just the video!
